* Basic implementation for server members and node status
* Commands for alloc status and job status
* -ui flag for most commands
* url hints for variables
* url hints for job dispatch, evals, and deployments
* agent config ui.cli_url_links to disable
* Fix an issue where path prefix was presumed for variables
* driver uncomment and general cleanup
* -ui flag on the generic status endpoint
* Job run command gets namespaces, and no longer gets ui hints for --output flag
* Dispatch command hints get a namespace, and bunch o tests
* Lots of tests depend on specific output, so let's not mess with them
* figured out what flagAddress is all about for testServer, oof
* Parallel outside of test instances
* Browser-opening test, sorta
* Env var for disabling/enabling CLI hints
* Addressing a few PR comments
* CLI docs available flags now all have -ui
* PR comments addressed; switched the env var to be consistent and scrunched monitor-adjacent hints a bit more
* ui.Output -> ui.Warn; moves hints from stdout to stderr
* isTerminal check and parseBool on command option
* terminal.IsTerminal check removed for test-runner-not-being-terminal reasons
The RPC handlers expect to see `nil` ACL objects whenever ACLs are disabled. By
using `nil` as a sentinel value, we have the risk of nil pointer exceptions and
improper handling of `nil` when returned from our various auth methods that can
lead to privilege escalation bugs. This is the third in a series to eliminate
the use of `nil` ACLs as a sentinel value for when ACLs are disabled.
This patch involves creating a new "virtual" ACL object for checking permissions
on client operations and a matching `AuthenticateClientOnly` method for
client-only RPCs that can produce that ACL.
Unlike the server ACLs PR, this also includes a special case for "legacy" client
RPCs where the client was not previously sending the secret as it
should (leaning on mTLS only). Those client RPCs were fixed in Nomad 1.6.0, but
it'll take a while before we can guarantee they'll be present during upgrades.

Implement the new `nomad job restart` command that allows operators to
restart allocations tasks or reschedule then entire allocation.
Restarts can be batched to target multiple allocations in parallel.
Between each batch the command can stop and hold for a predefined time
or until the user confirms that the process should proceed.
This implements the "Stateless Restarts" alternative from the original
RFC
(https://gist.github.com/schmichael/e0b8b2ec1eb146301175fd87ddd46180).
The original concept is still worth implementing, as it allows this
functionality to be exposed over an API that can be consumed by the
Nomad UI and other clients. But the implementation turned out to be more
complex than we initially expected so we thought it would be better to
release a stateless CLI-based implementation first to gather feedback
and validate the restart behaviour.

Most job subcommands allow for job ID prefix match as a convenience
functionality so users don't have to type the full job ID.
But this introduces a hard ACL requirement that the token used to run
these commands have the `list-jobs` permission, even if the token has
enough permission to execute the basic command action and the user
passed an exact job ID.
This change softens this requirement by not failing the prefix match in
case the request results in a permission denied error and instead using
the information passed by the user directly.
This PR fixes a flakey test where we did not wait on the check
status to actually become failing (go too fast and you just get
a pending check).
Instead add a helper for waiting on any check in the alloc to become
the state we are looking for.
This PR adds some NSD check status output to the CLI.
1. The 'nomad alloc status' command produces nsd check summary output (if present)
2. The 'nomad alloc checks' sub-command is added to produce complete nsd check output (if present)
This PR is the first of several for cleaning up warnings, and refactoring
bits of code in the command package. First pass is over acl_ files and
gets some helpers in place.
