Mark Anderson 10963d0cbd Add support for downstreams
Enhance config by adding SocketPath and LocalSocketPath config values

Supports syntax of the form:
```
services {
  name = "sock_forwarder"
  id = "sock_forwarder.1"
  socket_path = "/tmp/downstream_3.sock"
  connect {
    sidecar_service {
      proxy {
	local_service_socket_path = "/tmp/downstream.sock"
      }
    }
  }
}
```

Daniel Nephin 03aa6106ff connect/proxy: fix a number of problems with Listener
We noticed that TestUpstreamListener would deadlock sometimes when run
with the race detector. While debugging this issue I found and fixed the
following problems.

1. the net.Listener was not being closed properly when Listener.Stop was
   called. This caused the Listener.Serve goroutine to run forever.
   Fixed by storing a reference to net.Listener and closing it properly
   when Listener.Stop is called.
2. call connWG.Add in the correct place. WaitGroup.Add must be called
   before starting a goroutine, not from inside the goroutine.
3. Set metrics config EnableRuntimeMetrics to `false` so that we don't
   start a background goroutine in each test for no reason. There is no
   way to shutdown this goroutine, and it was an added distraction while
   debugging these timeouts.
5. two tests were calling require.NoError from a goroutine.
   require.NoError calls t.FailNow, which MUST be called from the main
   test goroutine. Instead use t.Errorf, which can be called from other
   goroutines and will still fail the test.
6. `assertCurrentGaugeValue` wass breaking out of a for loop, which
   would cause the `RWMutex.RUnlock` to be missed. Fixed by calling
   unlock before `break`.

The core issue of a deadlock  was fixed by https://github.com/armon/go-metrics/pull/124.

Daniel Nephin ef0999547a testing: skip slow tests with -short
Add a skip condition to all tests slower than 100ms.

This change was made using `gotestsum tool slowest` with data from the
last 3 CI runs of master.
See https://github.com/gotestyourself/gotestsum#finding-and-skipping-slow-tests

With this change:

```
$ time go test -count=1 -short ./agent
ok      github.com/hashicorp/consul/agent       0.743s

real    0m4.791s

$ time go test -count=1 -short ./agent/consul
ok      github.com/hashicorp/consul/agent/consul        4.229s

real    0m8.769s

Daniel Nephin a7fec642fc ci: go-test-race switch to exclude list
Most packages should pass the race detector. An exclude list ensures
that new packages are automatically tested with -race.

Also fix a couple small test races to allow more packages to be tested.

Returning readyCh requires a lock because it can be set to nil, and
setting it to nil will race without the lock.

Move the TestServer.Listening calls around so that they properly guard
setting TestServer.l. Otherwise it races.

Remove t.Parallel in a small package. The entire package tests run in a
few seconds, so t.Parallel does very little.

In auto-config, wait for the AutoConfig.run goroutine to stop before
calling readPersistedAutoConfig. Without this change there was a data
race on reading ac.config.

R.B. Boyer 5c5f21088c sdk: add freelist tracking and ephemeral port range skipping to freeport
This should cut down on test flakiness.

Problems handled:

- If you had enough parallel test cases running, the former circular
approach to handling the port block could hand out the same port to
multiple cases before they each had a chance to bind them, leading to
one of the two tests to fail.

- The freeport library would allocate out of the ephemeral port range.
This has been corrected for Linux (which should cover CI).

- The library now waits until a formerly-in-use port is verified to be
free before putting it back into circulation.

Move the watch package into the api module (#5664)
* Move the watch package into the api module

It was already just a thin wrapper around the API anyways. The biggest change was to the testing. Instead of using a test agent directly from the agent package it now uses the binary on the PATH just like the other API tests.

The other big changes were to fix up the connect based watch tests so that we didn’t need to pull in the connect package (and therefore all of Consul)

Paul Banks 979e1c9c94 Add -sidecar-for and new /agent/service/:service_id endpoint (#4691)
- A new endpoint `/v1/agent/service/:service_id` which is a generic way to look up the service for a single instance. The primary value here is that it:
   - **supports hash-based blocking** and so;
   - **replaces `/agent/connect/proxy/:proxy_id`** as the mechanism the built-in proxy uses to read its config.
   - It's not proxy specific and so works for any service.
   - It has a temporary shim to call through to the existing endpoint to preserve current managed proxy config defaulting behaviour until that is removed entirely (tested).
 - The built-in proxy now uses the new endpoint exclusively for it's config
 - The built-in proxy now has a `-sidecar-for` flag that allows the service ID of the _target_ service to be specified, on the condition that there is exactly one "sidecar" proxy (that is one that has `Proxy.DestinationServiceID` set) for the service registered.
 - Several fixes for edge cases for SidecarService
 - A fix for `Alias` checks - when running locally they didn't update their state until some external thing updated the target. If the target service has no checks registered as below, then the alias never made it past critical.

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
