Update go-msgpack version (#5683)
Fixes #4673
Supercedes: #5677 

There was an error decoding `map[string]string` values due to Go strings being immutable. This was fixes in our go-msgpack fork.

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.

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.

Paul Banks 3adfe86f03 Update Serf and memberlist (#4511)
This includes fixes that improve gossip scalability on very large (> 10k node) clusters.

The Serf changes:
 - take snapshot disk IO out of the critical path for handling messages hashicorp/serf#524
 - make snapshot compaction much less aggressive - the old fixed threshold caused snapshots to be constantly compacted (synchronously with request handling) on clusters larger than about 2000 nodes! hashicorp/serf#525

Memberlist changes:
 - prioritize handling alive messages over suspect/dead to improve stability, and handle queue in LIFO order to avoid acting on info that 's already stale in the queue by the time we handle it. hashicorp/memberlist#159
 - limit the number of concurrent pushPull requests being handled at once to 128. In one test scenario with 10s of thousands of servers we saw channel and lock blocking cause over 3000 pushPulls at once which ballooned the memory of the server because each push pull contained a de-serialised list of all known 10k+ nodes and their tags for a total of about 60 million objects and 7GB of memory stuck. While the rest of the fixes here should prevent the same root cause from blocking in the same way, this prevents any other bug or source of contention from allowing pushPull messages to stack up and eat resources. hashicorp/memberlist#158

Frank Schroeder 3d4fa7f65d Update github.com/hashicorp/go-discover to pull in new config parser
This patch updates the go-discover library to use the new config parser
which uses a different encoding scheme for the go-discover config DSL.
Values are no longer URL encoded but taken literally unless they contain
spaces, backslashes or double quotes. To support keys or values with
these special characters the string needs to be double quoted and usual
escaping rules apply.

Frank Schröder 69a088ca85 New config parser, HCL support, multiple bind addrs (#3480)
* new config parser for agent

This patch implements a new config parser for the consul agent which
makes the following changes to the previous implementation:

 * add HCL support
 * all configuration fragments in tests and for default config are
   expressed as HCL fragments
 * HCL fragments can be provided on the command line so that they
   can eventually replace the command line flags.
 * HCL/JSON fragments are parsed into a temporary Config structure
   which can be merged using reflection (all values are pointers).
   The existing merge logic of overwrite for values and append
   for slices has been preserved.
 * A single builder process generates a typed runtime configuration
   for the agent.

The new implementation is more strict and fails in the builder process
if no valid runtime configuration can be generated. Therefore,
additional validations in other parts of the code should be removed.

The builder also pre-computes all required network addresses so that no
address/port magic should be required where the configuration is used
and should therefore be removed.

* improve bind and advertise addr error handling

* go through builder using test coverage

* minimal update to the docs

* more coverage tests fixed

* more tests

* fix makefile

* cleanup

* fix port conflicts with external port server 'porter'

* stop test server on error

* do not run api test that change global ENV concurrently with the other tests

* Run remaining api tests concurrently

* no need for retry with the port number service

* monkey patch race condition in go-sockaddr until we understand why that fails

* monkey patch hcl decoder race condidtion until we understand why that fails

* monkey patch spurious errors in strings.EqualFold from here

* Gets rid of skipped TestAgent_CheckPerformanceSettings and adds case for builder.

* Add porter to server_test.go to make tests there less flaky

* go fmt

Updates memberlist and Serf (and adds new dependencies).
This gets a number of improvements:

* Fixed a missing case where gossip would stop flowing to dead nodes for a short while.
* Uses the go-sockaddr library to look for private IP addresses, which prefers non-loopback
  private addresses over loopback ones when trying to automatically determine the advertise address.
* Properly seeds Go's random number generator using the seed library.
* Serf snapshots no longer have the executable bit set on thie file.
