[BUGFIX] Fix race condition in freeport (#7567)
This removes a race condition in reset since pendingPorts can be set to nil in reset()

If ticker is hit at wrong time, it would crash the unit test.

We ensure in reset to avoid this race condition by cancelling the goroutine using
killTicker chan.

We also properly clean up eveything, so garbage collector can work as expected.

To reproduce existing bug:
`while go test -timeout 30s github.com/hashicorp/consul/sdk/freeport -run '^(Test.*)$'; do go clean -testcache; done`

Will crash after a few 10s runs on my machine.

Error could be seen in unit tests sometimes:

[INFO] freeport: resetting the freeport package state
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0x1125536]

Proper detection of ephemeral ports on Mac OS (#7539)
Use systemctl to properly detect ephemeral ports on Mac OS (aka darwin) by fetching
systemctl values:
 * net.inet.ip.portrange.first
 * net.inet.ip.portrange.last

This will avoid the message:

`[INFO] freeport: ephemeral port range detection not configured for GOOS="darwin"`

and properly detect the correct port range

Daniel Nephin 4d485649d1 ci: Use golangci-lint for linting
Using golangci-lint has a number of advantages:

- adding new linters becomes much easier, its a couple lines of yaml config
  instead of more bash scripting

- it enables whitelisting of issues using inline comments or regex

- when running multiple linters less work is done. The parsed source can be reused
  by multiple linters

- linters are run in parallel to reduce CI runtime.

connect: check if intermediate cert needs to be renewed. (#6835)
Currently when using the built-in CA provider for Connect, root certificates are valid for 10 years, however secondary DCs get intermediates that are valid for only 1 year. There is no mechanism currently short of rotating the root in the primary that will cause the secondary DCs to renew their intermediates.
This PR adds a check that renews the cert if it is half way through its validity period.

In order to be able to test these changes, a new configuration option was added: IntermediateCertTTL which is set extremely low in the tests.

sdk: ignore panics due to stray goroutines logging after a test completes (#6632)
If there is imperfect goroutine lifespan tracking if we pipe our logs
through testing.T.Logf there is a chance of a stray goroutine attempting
to log after the test that spawned it completes.

This results in a panic of:

    panic: Log in goroutine after TestLeader_SecondaryCA_Initialize has completed...

This isn't great and should be fixed, but quickly runs into situations
around externally cancelling blocking queries which isn't terribly
possible at the moment. The concession here is to ignore these specific
panics for now.

This can be triggered easily when running some tests with a high
`-count=YYY` value.

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.

Various Gateway Fixes (#6093)
* Ensure the mesh gateway configuration comes back in the api within each upstream

* Add a test for the MeshGatewayConfig in the ToAPI functions

* Ensure we don’t use gateways for dc local connections

* Update the svc kind index for deletions

* Replace the proxycfg.state cache with an interface for testing

Also start implementing proxycfg state testing.

* Update the state tests to verify some gateway watches for upstream-targets of a discovery chain.

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

Matt Keeler ea6cbf01a5 Centralized Config CLI (#5731)
* Add HTTP endpoints for config entry management

* Finish implementing decoding in the HTTP Config entry apply endpoint

* Add CAS operation to the config entry apply endpoint

Also use this for the bootstrapping and move the config entry decoding function into the structs package.

* First pass at the API client for the config entries

* Fixup some of the ConfigEntry APIs

Return a singular response object instead of a list for the ConfigEntry.Get RPC. This gets plumbed through the HTTP API as well.

Dont return QueryMeta in the JSON response for the config entry listing HTTP API. Instead just return a list of config entries.

* Minor API client fixes

* Attempt at some ConfigEntry api client tests

These don’t currently work due to weak typing in JSON

* Get some of the api client tests passing

* Implement reflectwalk magic to correct JSON encoding a ProxyConfigEntry

Also added a test for the HTTP endpoint that exposes the problem. However, since the test doesn’t actually do the JSON encode/decode its still failing.

* Move MapWalk magic into a binary marshaller instead of JSON.

* Add a MapWalk test

* Get rid of unused func

* Get rid of unused imports

* Fixup some tests now that the decoding from msgpack coerces things into json compat types

* Stub out most of the central config cli

Fully implement the config read command.

* Basic config delete command implementation

* Implement config write command

* Implement config list subcommand

Not entirely sure about the output here. Its basically the read output indented with a line specifying the kind/name of each type which is also duplicated in the indented output.

* Update command usage

* Update some help usage formatting

* Add the connect enable helper cli command

* Update list command output

* Rename the config entry API client methods.

* Use renamed apis

* Implement config write tests

Stub the others with the noTabs tests.

* Change list output format

Now just simply output 1 line per named config

* Add config read tests

* Add invalid args write test.

* Add config delete tests

* Add config list tests

* Add connect enable tests

* Update some CLI commands to use CAS ops

This also modifies the HTTP API for a write op to return a boolean indicating whether the value was written or not.

* Fix up the HTTP API CAS tests as I realized they weren’t testing what they should.

* Update config entry rpc tests to properly test CAS

* Fix up a few more tests

* Fix some tests that using ConfigEntries.Apply

* Update config_write_test.go

* Get rid of unused import
