Upgrade go-connlimit to v0.3.0 / return http 429 on too many connections (#8221)
Fixes #7527

I want to highlight this and explain what I think the implications are and make sure we are aware:

* `HTTPConnStateFunc` closes the connection when it is beyond the limit. `Close` does not block.
* `HTTPConnStateFuncWithDefault429Handler(10 * time.Millisecond)` blocks until the following is done (worst case):
  1) `conn.SetDeadline(10*time.Millisecond)` so that
  2) `conn.Write(429error)` is guaranteed to timeout after 10ms, so that the http 429 can be written and 
  3) `conn.Close` can happen

The implication of this change is that accepting any new connection is worst case delayed by 10ms. But only after a client reached the limit already.

Update gopsutil (#8208)
https://github.com/shirou/gopsutil/pull/895 is merged and fixes our
problem. Time to update. Since there is no new version just yet,
updating to the sha.

Add a test for go routine leaks
This is in its own separate package so that it will be a separate test binary that runs thus isolating the go runtime from other tests and allowing accurate go routine leak checking.

This test would ideally use goleak.VerifyTestMain but that will fail 100% of the time due to some architectural things (blocking queries and net/rpc uncancellability).

This test is not comprehensive. We should enable/exercise more features and more cluster configurations. However its a start.

Daniel Nephin 221a49f430 Update protobuf and golang.org/x/... vendor
Partially extracted from #7547

Updates protobuf to the most recent in the 1.3.x series, and updates
golang.org/x/sys to a7d97aace0b0 because of https://github.com/shirou/gopsutil/issues/853
prevents updating to a more recent version.

This breaking change in x/sys also prevents us from getting a newer
version of x/net. In the future, if gopsutil is not patched,  we may want to run a fork version of
gopsutil so that we can update both x/net and x/sys.

Replace goe/verify.Values with testify/require.Equal (#7993)
* testing: replace most goe/verify.Values with require.Equal

One difference between these two comparisons is that go/verify considers
nil slices/maps to be equal to empty slices/maps, where as testify/require
does not, and does not appear to provide any way to enable that behaviour.

Because of this difference some expected values were changed from empty
slices to nil slices, and some calls to verify.Values were left.

* Remove github.com/pascaldekloe/goe/verify

Reduce the number of assertion packages we use from 2 to 1

wan federation via mesh gateways (#6884)
This is like a Möbius strip of code due to the fact that low-level components (serf/memberlist) are connected to high-level components (the catalog and mesh-gateways) in a twisty maze of references which make it hard to dive into. With that in mind here's a high level summary of what you'll find in the patch:

There are several distinct chunks of code that are affected:

* new flags and config options for the server

* retry join WAN is slightly different

* retry join code is shared to discover primary mesh gateways from secondary datacenters

* because retry join logic runs in the *agent* and the results of that
  operation for primary mesh gateways are needed in the *server* there are
  some methods like `RefreshPrimaryGatewayFallbackAddresses` that must occur
  at multiple layers of abstraction just to pass the data down to the right
  layer.

* new cache type `FederationStateListMeshGatewaysName` for use in `proxycfg/xds` layers

* the function signature for RPC dialing picked up a new required field (the
  node name of the destination)

* several new RPCs for manipulating a FederationState object:
  `FederationState:{Apply,Get,List,ListMeshGateways}`

* 3 read-only internal APIs for debugging use to invoke those RPCs from curl

* raft and fsm changes to persist these FederationStates

* replication for FederationStates as they are canonically stored in the
  Primary and replicated to the Secondaries.

* a special derivative of anti-entropy that runs in secondaries to snapshot
  their local mesh gateway `CheckServiceNodes` and sync them into their upstream
  FederationState in the primary (this works in conjunction with the
  replication to distribute addresses for all mesh gateways in all DCs to all
  other DCs)

* a "gateway locator" convenience object to make use of this data to choose
  the addresses of gateways to use for any given RPC or gossip operation to a
  remote DC. This gets data from the "retry join" logic in the agent and also
  directly calls into the FSM.

* RPC (`:8300`) on the server sniffs the first byte of a new connection to
  determine if it's actually doing native TLS. If so it checks the ALPN header
  for protocol determination (just like how the existing system uses the
  type-byte marker).

* 2 new kinds of protocols are exclusively decoded via this native TLS
  mechanism: one for ferrying "packet" operations (udp-like) from the gossip
  layer and one for "stream" operations (tcp-like). The packet operations
  re-use sockets (using length-prefixing) to cut down on TLS re-negotiation
  overhead.

* the server instances specially wrap the `memberlist.NetTransport` when running
  with gateway federation enabled (in a `wanfed.Transport`). The general gist is
  that if it tries to dial a node in the SAME datacenter (deduced by looking
  at the suffix of the node name) there is no change. If dialing a DIFFERENT
  datacenter it is wrapped up in a TLS+ALPN blob and sent through some mesh
  gateways to eventually end up in a server's :8300 port.

* a new flag when launching a mesh gateway via `consul connect envoy` to
  indicate that the servers are to be exposed. This sets a special service
  meta when registering the gateway into the catalog.

* `proxycfg/xds` notice this metadata blob to activate additional watches for
  the FederationState objects as well as the location of all of the consul
  servers in that datacenter.

* `xds:` if the extra metadata is in place additional clusters are defined in a
  DC to bulk sink all traffic to another DC's gateways. For the current
  datacenter we listen on a wildcard name (`server.<dc>.consul`) that load
  balances all servers as well as one mini-cluster per node
  (`<node>.server.<dc>.consul`)

* the `consul tls cert create` command got a new flag (`-node`) to help create
  an additional SAN in certs that can be used with this flavor of federation.

This only works so long as we use simplistic protobuf types. Constructs such as oneof or Any types that require type annotations for decoding properly will fail hard but that is by design. If/when we want to use any of that we will probably need to consider a v2 API.

Generate JSON and Binary Marshalers for Protobuf Types (#6564)
* Add JSON and Binary Marshaler Generators for Protobuf Types

* Generate files with the correct version of gogo/protobuf

I have pinned the version in the makefile so when you run make tools you get the right version. This pulls the version out of go.mod so it should remain up to date.

The version at the time of this commit we are using is v1.2.1

* Fixup some shell output

* Update how we determine the version of gogo
This just greps the go.mod file instead of expecting the go mod cache to already be present

* Fixup vendoring and remove no longer needed json encoder functions

Expand the QueryOptions and QueryMeta interfaces (#6545)
In a previous PR I made it so that we had interfaces that would work enough to allow blockingQueries to work. However to complete this we need all fields to be settable and gettable.

Notes:
   • If Go ever gets contracts/generics then we could get rid of all the Getters/Setters
   • protoc / protoc-gen-gogo are going to generate all the getters for us.
   • I copied all the getters/setters from the protobuf funcs into agent/structs/protobuf_compat.go
   • Also added JSON marshaling funcs that use jsonpb for protobuf types.

connect: intermediate CA certs generated with the vault provider lack URI SANs (#6491)
This only affects vault versions >=1.1.1 because the prior code
accidentally relied upon a bug that was fixed in
https://github.com/hashicorp/vault/pull/6505

The existing tests should have caught this, but they were using a
vendored copy of vault version 0.10.3. This fixes the tests by running
an actual copy of vault instead of an in-process copy. This has the
added benefit of changing the dependency on vault to just vault/api.

Also update VaultProvider to use similar SetIntermediate validation code
as the ConsulProvider implementation.

Add support for implementing new requests with protobufs instea… (#6502)
* Add build system support for protobuf generation

This is done generically so that we don’t have to keep updating the makefile to add another proto generation.

Note: anything not in the vendor directory and with a .proto extension will be run through protoc if the corresponding namespace.pb.go file is not up to date.

If you want to rebuild just a single proto file you can do so with: make proto-rebuild PROTOFILES=<list of proto files to rebuild>

Providing the PROTOFILES var will override the default behavior of finding all the .proto files.

* Start adding types to the agent/proto package

These will be needed for some other work and are by no means comprehensive.

* Add ability to resolve/fixup the agentpb.ACLLinks structure in the state store.

* Use protobuf marshalling of raft requests instead of msgpack for protoc generated types.

This does not change any encoding of existing types.

* Removed structs package automatically encoding with protobuf marshalling

Instead the caller of raftApply that wants to opt-in to protobuf encoding will have to call `raftApplyProtobuf`

* Run update-vendor to fixup modules.txt

Nothing changed as far as dependencies go but the ordering of modules in that file depends on the time they are first seen and its not alphabetical.

* Rename some things and implement the structs.RPCInfo interface bits

agentpb.QueryOptions and agentpb.WriteRequest implement 3 of the 4 RPCInfo funcs and the new TargetDatacenter message type implements the fourth.

* Use the right encoding function.

* Renamed agent/proto package to agent/agentpb to prevent package name conflicts

* Update modules.txt to fix ordering

* Change blockingQuery to take in interfaces for the query options and meta

* Add %T to error output.

* Add/Update some comments
