connect: intentions are now managed as a new config entry kind "service-intentions" (#8834)
- Upgrade the ConfigEntry.ListAll RPC to be kind-aware so that older
copies of consul will not see new config entries it doesn't understand
replicate down.

- Add shim conversion code so that the old API/CLI method of interacting
with intentions will continue to work so long as none of these are
edited via config entry endpoints. Almost all of the read-only APIs will
continue to function indefinitely.

- Add new APIs that operate on individual intentions without IDs so that
the UI doesn't need to implement CAS operations.

- Add a new serf feature flag indicating support for
intentions-as-config-entries.

- The old line-item intentions way of interacting with the state store
will transparently flip between the legacy memdb table and the config
entry representations so that readers will never see a hiccup during
migration where the results are incomplete. It uses a piece of system
metadata to control the flip.

- The primary datacenter will begin migrating intentions into config
entries on startup once all servers in the datacenter are on a version
of Consul with the intentions-as-config-entries feature flag. When it is
complete the old state store representations will be cleared. We also
record a piece of system metadata indicating this has occurred. We use
this metadata to skip ALL of this code the next time the leader starts
up.

- The secondary datacenters continue to run the old intentions
replicator until all servers in the secondary DC and primary DC support
intentions-as-config-entries (via serf flag). Once this condition it met
the old intentions replicator ceases.

- The secondary datacenters replicate the new config entries as they are
migrated in the primary. When they detect that the primary has zeroed
it's old state store table it waits until all config entries up to that
point are replicated and then zeroes its own copy of the old state store
table. We also record a piece of system metadata indicating this has
occurred. We use this metadata to skip ALL of this code the next time
the leader starts up.

Daniel Nephin 71e51263be sdk: mitigate api test timeout
Occasionally we are seeing the go-test-api job timeout at 10 minutes.
Looking at the stack trace I saw the following:

1. Lots of tests blocked on server.Stop in NewTestServerConfigT. This
   suggests that SIGINT is being sent to the server, but the server is
   not properly shutting down.

2. Over 20k goroutines that look like this:

goroutine 16355 [select, 8 minutes]:
net/http.(*persistConn).readLoop(0xc004270240)
    /usr/local/go/src/net/http/transport.go:2099 +0x99e
created by net/http.(*Transport).dialConn
    /usr/local/go/src/net/http/transport.go:1647 +0xc56

Issue 1 seems to be the main problem, but debugging that directly is not
possible because our buffered logs do not get sent when the tests
timeout. To mitigate this problem I've added a timeout to the cmd.Wait()
to force kill the process and return an error.

Unfortunately because we retry this operation, we still may not see the
cause because the next attempt will likely pass. I'm tempted to remove
the retry around NewTestServerConfigT.

Issue 2 seems to be caused by not closing the response body. Since the
request is performed many times in a loop, many goroutines are created
and are not closed until the response body is closed.

Daniel Nephin 80ff174880 testutil: NewLogBuffer - buffer logs until a test fails
Replaces #7559

Running tests in parallel, with background goroutines, results in test output not being associated with the correct test. `go test` does not make any guarantees about output from goroutines being attributed to the correct test case.

Attaching log output from background goroutines also cause data races.  If the goroutine outlives the test, it will race with the test being marked done. Previously this was noticed as a panic when logging, but with the race detector enabled it is shown as a data race.

The previous solution did not address the problem of correct test attribution because test output could still be hidden when it was associated with a test that did not fail. You would have to look at all of the log output to find the relevant lines. It also made debugging test failures more difficult because each log line was very long.

This commit attempts a new approach. Instead of printing all the logs, only print when a test fails. This should work well when there are a small number of failures, but may not work well when there are many test failures at the same time. In those cases the failures are unlikely a result of a specific test, and the log output is likely less useful.

All of the logs are printed from the test goroutine, so they should be associated with the correct test.

Also removes some test helpers that were not used, or only had a single caller. Packages which expose many functions with similar names can be difficult to use correctly.

sdk: Use /v1/status/leader endpoint when starting a test server (#8192)
Switch from /v1/agent/self to /v1/status/leader when checking if the test server has come up successfully in the waitForAPI function.

Previously, the test server was relying (probably not intentionally) on the default value of the acl_enforce_version_8 in the TestConfig, which was false. So if you create a test server and enabled ACLs, they would not be enforced and the server would be able to come up pretty quickly because /v1/agent/self would return a 200 status pretty much as soon as the agent is running and most likely before leader election is finished.

Now that we have removed acl_enforce_version_8 property (equivalent to being true by default) if you've created a test server with ACLs enabled, it will need to wait for leader election and for ACLs to be initialized before it'll get a successful response from the /v1/agent/self.

Note: With this change, waitForAPI function no longer requires a 200 response status from the v1/status/leader endpoint. This is because in some tests, namely TestAPI_AgentLeave, we are only running clients, and this endpoint returns a 500 status.

Nil checks in the testWriter to prevent using a bad testing.TB (#6517)
Also needed to update some funcs that were taking a *testing.T to use a testing.TB. This prevents passing a nil pointer as a non-nil interface value
and thus making it impossible to detect nil before using the interfaces functions.

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.

Update TestServer creation in sdk/testutil (#6084)
* Retry the creation of the test server three times.
* Reduce the retry timeout for the API wait to 2 seconds, opting to fail faster and start over.
* Remove wait for leader from server creation. This wait can be added on a test by test basis now that the function is being exported.
* Remove wait for anti-entropy sync. This is built into the existing WaitForSerfCheck func, so that can be used if the anti-entropy wait is needed
