Kyle Havlovitz e7946197b8 connect/ca: prevent blank CA config in snapshot
This PR both prevents a blank CA config from being written out to
a snapshot and allows Consul to gracefully recover from a snapshot
with an invalid CA config.

Fixes #4954.

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.

* command/debug: implementation of static capture

* command/debug: tests and only configured targets

* vendor: add gopsutil/disk

* command/debug: add a usage section

* website: add docs for consul debug

* agent/host: require operator:read

* api/host: improve docs and no retry timing

* command/debug: fail on extra arguments

* command/debug: fixup file permissions to 0644

* command/debug: remove server flags

* command/debug: improve clarity of usage section

* api/debug: add Trace for profiling, fix profile

* command/debug: capture profile and trace at the same time

* command/debug: add index document

* command/debug: use "clusters" in place of members

* command/debug: remove address in output

* command/debug: improve comment on metrics sleep

* command/debug: clarify usage

* agent: always register pprof handlers and protect

This will allow us to avoid a restart of a target agent
for profiling by always registering the pprof handlers.

Given this is a potentially sensitive path, it is protected
with an operator:read ACL and enable debug being
set to true on the target agent. enable_debug still requires
a restart.

If ACLs are disabled, enable_debug is sufficient.

* command/debug: use trace.out instead of .prof

More in line with golang docs.

* agent: fix comment wording

* agent: wrap table driven tests in t.run()

fix some test hangs (#4785)
The default http.Client uses infinite timeouts, so if TestHTTPAPI_MethodNotAllowed_OSS experienced anything going wrong about setup it could hang forever.

Switching to hard coding various http.Client timeouts to non-infinite values at least bounds the failure time.

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 b0fc91a1d2 [Performance On Large clusters] Reduce updates on large services (#4720)
* [Performance On Large clusters] Checks do update services/nodes only when really modified to avoid too many updates on very large clusters

In a large cluster, when having a few thousands of nodes, the anti-entropy
mechanism performs lots of changes (several per seconds) while
there is no real change. This patch wants to improve this in order
to increase Consul scalability when using many blocking requests on
health for instance.

* [Performance for large clusters] Only updates index of service if service is really modified

* [Performance for large clusters] Only updates index of nodes if node is really modified

* Added comments / ensure IsSame() has clear semantics

* Avoid having modified boolean, return nil directly if stutures are Same

* Fixed unstable unit tests TestLeader_ChangeServerID

* Rewrite TestNode_IsSame() for better readability as suggested by @banks

* Rename ServiceNode.IsSame() into IsSameService() + added unit tests

* Do not duplicate TestStructs_ServiceNode_Conversions() and increase test coverage of IsSameService

* Clearer documentation in IsSameService

* Take into account ServiceProxy into ServiceNode.IsSameService()

* Fixed IsSameService() with all new structures

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:
```
