Daniel Nephin dfa8856e5f agent/consul: Add support for NotModified to two endpoints
A query made with AllowNotModifiedResponse and a MinIndex, where the
result has the same Index as MinIndex, will return an empty response
with QueryMeta.NotModified set to true.

Aestek 04a52a967b acl: allow service deregistration with node write permission (#5217)
With ACLs enabled if an agent is wiped and restarted without a leave
it can no longer deregister the services it had previously registered
because it no longer has the tokens the services were registered with.
To remedy that we allow service deregistration from tokens with node
write permission.

Implement data filtering of some endpoints (#5579)
Fixes: #4222 

# Data Filtering

This PR will implement filtering for the following endpoints:

## Supported HTTP Endpoints

- `/agent/checks`
- `/agent/services`
- `/catalog/nodes`
- `/catalog/service/:service`
- `/catalog/connect/:service`
- `/catalog/node/:node`
- `/health/node/:node`
- `/health/checks/:service`
- `/health/service/:service`
- `/health/connect/:service`
- `/health/state/:state`
- `/internal/ui/nodes`
- `/internal/ui/services`

More can be added going forward and any endpoint which is used to list some data is a good candidate.

## Usage

When using the HTTP API a `filter` query parameter can be used to pass a filter expression to Consul. Filter Expressions take the general form of:

```
<selector> == <value>
<selector> != <value>
<value> in <selector>
<value> not in <selector>
<selector> contains <value>
<selector> not contains <value>
<selector> is empty
<selector> is not empty
not <other expression>
<expression 1> and <expression 2>
<expression 1> or <expression 2>
```

Normal boolean logic and precedence is supported. All of the actual filtering and evaluation logic is coming from the [go-bexpr](https://github.com/hashicorp/go-bexpr) library

## Other changes

Adding the `Internal.ServiceDump` RPC endpoint. This will allow the UI to filter services better.

Pierre Souchay 5b8a7d7127 Avoid to have infinite recursion in DNS lookups when resolving CNAMEs (#4918)
* Avoid to have infinite recursion in DNS lookups when resolving CNAMEs

This will avoid killing Consul when a Service.Address is using CNAME
to a Consul CNAME that creates an infinite recursion.

Fix catalog service node filtering (ex /v1/catalog/service/srv?tag=tag1)

New server version did not account for the old field when filtering
hence request made from old agent were not tag-filtered.

New ACLs (#4791)
This PR is almost a complete rewrite of the ACL system within Consul. It brings the features more in line with other HashiCorp products. Obviously there is quite a bit left to do here but most of it is related docs, testing and finishing the last few commands in the CLI. I will update the PR description and check off the todos as I finish them over the next few days/week.
Description

At a high level this PR is mainly to split ACL tokens from Policies and to split the concepts of Authorization from Identities. A lot of this PR is mostly just to support CRUD operations on ACLTokens and ACLPolicies. These in and of themselves are not particularly interesting. The bigger conceptual changes are in how tokens get resolved, how backwards compatibility is handled and the separation of policy from identity which could lead the way to allowing for alternative identity providers.

On the surface and with a new cluster the ACL system will look very similar to that of Nomads. Both have tokens and policies. Both have local tokens. The ACL management APIs for both are very similar. I even ripped off Nomad's ACL bootstrap resetting procedure. There are a few key differences though.

    Nomad requires token and policy replication where Consul only requires policy replication with token replication being opt-in. In Consul local tokens only work with token replication being enabled though.
    All policies in Nomad are globally applicable. In Consul all policies are stored and replicated globally but can be scoped to a subset of the datacenters. This allows for more granular access management.
    Unlike Nomad, Consul has legacy baggage in the form of the original ACL system. The ramifications of this are:
        A server running the new system must still support other clients using the legacy system.
        A client running the new system must be able to use the legacy RPCs when the servers in its datacenter are running the legacy system.
        The primary ACL DC's servers running in legacy mode needs to be a gate that keeps everything else in the entire multi-DC cluster running in legacy mode.

So not only does this PR implement the new ACL system but has a legacy mode built in for when the cluster isn't ready for new ACLs. Also detecting that new ACLs can be used is automatic and requires no configuration on the part of administrators. This process is detailed more in the "Transitioning from Legacy to New ACL Mode" section below.

Rebecca Zanzig 0ec6d880f5 Support multiple tags for health and catalog http api endpoints (#4717)
* Support multiple tags for health and catalog api endpoints

Fixes #1781.

Adds a `ServiceTags` field to the ServiceSpecificRequest to support
multiple tags, updates the filter logic in the catalog store, and
propagates these change through to the health and catalog endpoints.

Note: Leaves `ServiceTag` in the struct, since it is being used as
part of the DNS lookup, which in turn uses the health check.

* Update the api package to support multiple tags

Includes additional tests.

* Update new tests to use the `require` library

* Update HealthConnect check after a bad merge

Pierre Souchay 42f250fa53 Added SOA configuration for DNS settings. (#4714)
This will allow to fine TUNE SOA settings sent by Consul in DNS responses,
for instance to be able to control negative ttl.

Will fix: https://github.com/hashicorp/consul/issues/4713

# Example

Override all settings:

* min_ttl: 0 => 60s
* retry: 600 (10m) => 300s (5 minutes),
* expire: 86400 (24h) => 43200 (12h)
* refresh: 3600 (1h) => 1800 (30 minutes)

```
consul agent -dev -hcl 'dns_config={soa={min_ttl=60,retry=300,expire=43200,refresh=1800}}'
```

Result:
```

Paul Banks 92fe8c8e89 Add Proxy Upstreams to Service Definition (#4639)
* Refactor Service Definition ProxyDestination.

This includes:
 - Refactoring all internal structs used
 - Updated tests for both deprecated and new input for:
   - Agent Services endpoint response
   - Agent Service endpoint response
   - Agent Register endpoint
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Register
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Services endpoint response
   - Catalog Node endpoint response
   - Catalog Service endpoint response
 - Updated API tests for all of the above too (both deprecated and new forms of register)

TODO:
 - config package changes for on-disk service definitions
 - proxy config endpoint
 - built-in proxy support for new fields

* Agent proxy config endpoint updated with upstreams

* Config file changes for upstreams.

* Add upstream opaque config and update all tests to ensure it works everywhere.

* Built in proxy working with new Upstreams config

* Command fixes and deprecations

* Fix key translation, upstream type defaults and a spate of other subtele bugs found with ned to end test scripts...

TODO: tests still failing on one case that needs a fix. I think it's key translation for upstreams nested in Managed proxy struct.

* Fix translated keys in API registration.
≈

* Fixes from docs
 - omit some empty undocumented fields in API
 - Bring back ServiceProxyDestination in Catalog responses to not break backwards compat - this was removed assuming it was only used internally.

* Documentation updates for Upstreams in service definition

* Fixes for tests broken by many refactors.

* Enable travis on f-connect branch in this branch too.

* Add consistent Deprecation comments to ProxyDestination uses

* Update version number on deprecation notices, and correct upstream datacenter field with explanation in docs

James Phillips fcaa889116 Bumps default Raft protocol to version 3. (#3477)
* Changes default Raft protocol to 3.

* Changes numPeers() to report only voters.

This should have been there before, but it's more obvious that this
is incorrect now that we default the Raft protocol to 3, which puts
new servers in a read-only state while Autopilot waits for them to
become healthy.

* Fixes TestLeader_RollRaftServer.

* Fixes TestOperator_RaftRemovePeerByAddress.

* Fixes TestServer_*.

Relaxed the check for a given number of voter peers and instead do
a thorough check that all servers see each other in their Raft
configurations.

* Fixes TestACL_*.

These now just check for Raft replication to be set up, and don't
care about the number of voter peers.

* Fixes TestOperator_Raft_ListPeers.

* Fixes TestAutopilot_CleanupDeadServerPeriodic.

* Fixes TestCatalog_ListNodes_ConsistentRead_Fail.

* Fixes TestLeader_ChangeServerID and adjusts the conn pool to throw away
sockets when it sees io.EOF.

* Changes version to 1.0.0 in the options doc.

* Makes metrics test more deterministic with autopilot metrics possible.

Frank Schröder 44e6b8122d acl: consolidate error handling (#3401)
The error handling of the ACL code relies on the presence of certain
magic error messages. Since the error values are sent via RPC between
older and newer consul agents we cannot just replace the magic values
with typed errors and switch to type checks since this would break
compatibility with older clients.

Therefore, this patch moves all magic ACL error messages into the acl
package and provides default error values and helper functions which
determine the type of error.
