Includes:

* Remove leader upgrade raft version test, as older versions of raft are now
  incompatible with our autopilot library.

* Remove attempt to assert initial non-voter status on the `PromoteNonVoter`
  test, as this happens too quickly to reliably detect.

* Unskip some previously-skipped tests which we should make stable.

* Remove the `consul/sdk` retry helper for these tests; this uses panic recovery
  in a kind of a clever/gross way to reduce LoC but it seems to introduce some
  timing issues in the process.

* Add more test step logging and reduce logging noise from the scheduler
  goroutines to make it easier to debug failing tests.

* Be more consistent about using the `waitForStableLeadership` helper so that we
  can assert the cluster is fully stable and not just that we've added peers.

Network quotas were removed in Nomad 1.0.4. Remove the fields no longer in use
from the `quota status` output.

Different mesage when there are not tasks in a job

Added a missing `continue` on non-nil error to avoid accidentally using a bad peer.

When configuring Consul Service Mesh, it's sometimes necessary to
provide dynamic value that are only known to Nomad at runtime. By
interpolating configuration values (in addition to configuration keys),
user are able to pass these dynamic values to Consul from their Nomad
jobs.

Nomad's original autopilot was importing from a private package in Consul. It
has been moved out to a shared library. Switch Nomad to use this library so that
we can eliminate the import of Consul, which is necessary to build Nomad ENT
with the current version of the Consul SDK. This also will let us pick up
autopilot improvements shared with Consul more easily.

These options are mutually exclusive but, since `-hcl2-strict` defaults
to `true` users had to explicitily set it to `false` when using `-hcl1`.

Also return `255` when job plan fails validation as this is the expected 
code in this situation.

Nomad is generally compliant with the CSI specification for Container
Orchestrators (CO), except for unimplemented features. However, some storage
vendors have built CSI plugins that are not compliant with the specification or
which expect that they're only deployed on Kubernetes. Nomad cannot vouch for
the compatibility of any particular plugin, so clarify this in the docs.

Log lines which include an error should use the full term "error"
as the context key. This provides consistency across the codebase
and avoids a Go style which operators might not be aware of.

In order to add an E2E test to cover token expiration, the server
config has been updated to include a low minimum allowed TTL
value. For ease of reading, the max value is also set.

It is really unclear on how to use this feature. it took me a while to find this, so I thought I would purpose how to use this.

The ACL command docs are now found within a sub-dir like the
operator command docs. Updates to the ACL token commands to
accommodate token expiry have also been added.

The ACL API docs are now found within a sub-dir like the operator
API docs. The ACL docs now include the ACL roles endpoint as well
as updated ACL token endpoints for token expiration.

The configuration section is also updated to accommodate the new
ACL and server parameters for the new ACL features.

This adds a new ACL test suite to the e2e framework which includes
an initial test for ACL roles. The ACL test includes a helper to
track and clean created Nomad resources which keeps the test
cluster clean no matter if the test fails early or not.

PR #12130 refactored the test to use the `wantPeers` helper, but this
function only returns the number of voting peers, which in this test
should be equal to 2.

I think the tests were passing back them because of a bug in Raft
(https://github.com/hashicorp/raft/pull/483) where a non-voting server
was able to transition to candidate state.

One possible evidence of this is that a successful test run would have
the following log line:

```
raft@v1.3.5/raft.go:1058: nomad.raft: updating configuration: command=AddVoter server-id=127.0.0.1:9101 server-addr=127.0.0.1:9101 servers="[{Suffrage:Voter ID:127.0.0.1:9107 Address:127.0.0.1:9107} {Suffrage:Voter ID:127.0.0.1:9105 Address:127.0.0.1:9105} {Suffrage:Voter ID:127.0.0.1:9103 Address:127.0.0.1:9103} {Suffrage:Voter ID:127.0.0.1:9101 Address:127.0.0.1:9101}]"
```

This commit reverts the test logic to check for peer count, regardless
of voting status.

* Update Consul Template dep to support Nomad vars

* Remove `Peering` config for Consul Testservers
Upgrading to the 1.14 Consul SDK introduces and additional default
configuration—`Peering`—that is not compatible with versions of Consul
before v1.13.0. because Nomad tests against Consul v1.11.1, this
configuration has to be nil'ed out before passing it to the Consul
binary.

Neither the `os.Setenv` nor `t.Setenv` helper are safe to use in parallel tests
because environment variables are process-global. The stdlib panics if you try
to do this. Remove the `ci.Parallel()` call from all tests where we're setting
environment variables.

Update the on-disk format for the root key so that it's wrapped with a unique
per-key/per-server key encryption key. This is a bit of security theatre for the
current implementation, but it uses `go-kms-wrapping` as the interface for
wrapping the key. This provides a shim for future support of external KMS such
as cloud provider APIs or Vault transit encryption.

* Removes the JSON serialization extension we had on the `RootKey` struct; this
  struct is now only used for key replication and not for disk serialization, so
  we don't need this helper.

* Creates a helper for generating cryptographically random slices of bytes that
  properly accounts for short reads from the source.

* No observable functional changes outside of the on-disk format, so there are
  no test updates.
