### Description
Pattern matching was [recently added](https://github.com/hashicorp/crt-orchestrator/pull/51) so that teams no longer have to explicitly list every branch that should trigger the CRT pipeline. This simplifies release preparation- anytime a new release branch is created, it will produce releasable artifacts and exercise the full pipeline.

### Testing & Reproduction steps
This has been tested in multiple projects since being rolled out. There are no nomad-specific tests that need to be done.

### Links
PR where this functionality was added: https://github.com/hashicorp/crt-orchestrator/pull/51

### PR Checklist

* [ ] updated test coverage
* [ ] external facing docs updated
* [X] not a security concern

checks: better goroutine handling for test tcp server

This PR hopefully fixes a race condition of our little test tcp server
that the check observer is making connections against for test cases.

The tcp listener would either startup too slow or exit too soon.

build: update aws env cpu info

Includes concept docs for secure variables, concept docs for workload
identity, and an operations docs for keyring management.

* Allow specification of CSI staging and publishing directory path
* Add website documentation for stage_publish_dir
* Replace erroneous reference to csi_plugin.mount_config with csi_plugin.mount_dir
* Avoid requiring CSI plugins to be redeployed after introducing StagePublishDir

Move the secure variables quota enforcement calls into the state store to ensure
quota checks are atomic with quota updates (in the same transaction).

Switch to a machine-size int instead of a uint64 for quota tracking. The
ENT-side quota spec is described as int, and negative values have a meaning as
"not permitted at all". Using the same type for tracking will make it easier to
the math around checks, and uint64 is infeasibly large anyways.

Add secure vars to quota HTTP API and CLI outputs and API docs.

build: update to go1.18.5

* refact:  namespace should be bound property

* chore: pass bound namespace property in template

* chore: update tests to account for bound namespace refactoring

* test: add test coverage for factoring namespace in path matching algo

This PR continues work we've started on other test suites to use the native
golang test runner instead of the custom framework.

deps: update raft library

deps: update test package

Another attempt at resolving the flakey TestNomad_BootstrapExpect_NonVoter

Upgrading to v0.3.0 gives us the ability to add more context to test
case failures.

https://github.com/shoenig/test/pull/23

This test is a fairly trivial test of the agent RPC, but the test setup waits
for a short fixed window after the node starts to send the RPC. After looking at
detailed logs for recent test failures, it looks like the node registration for
the first node doesn't get a chance to happen before we make the RPC call. Use
`WaitForResultUntil` to give the test more time to run in slower test
environments, while allowing it to finish quickly if possible.

OOM detection under cgroups v2 is flaky under versions of `containerd` before
v1.6.3, but our `containerd` dependency is transitive on `moby/moby`, who have
not yet updated. Disable this test for cgroups v2 environments until we can
update the dependency chain.

The `golang.org/x/net/context` package was merged into the stdlib as of go
1.7. Update the imports to use the identical stdlib version. Clean up import
blocks for the impacted files to remove unnecessary package aliasing.

website: enable setting custom tool for launching website dev container

When working in a podman environment, it's nice to just run the website
development container using podman.

cleanup: remove unneeded darwin lib

When we delete a namespace, we check to ensure that there are no non-terminal
jobs or CSI volume, which also covers evals, allocs, etc. Secure variables are
also namespaces, so extend this check to them as well.

cleanup: use constants for on_update values

When we delete a namespace, we check to ensure that there are no non-terminal
jobs, which effectively covers evals, allocs, etc. CSI volumes are also
namespaced, so extend this check to cover CSI volumes.
