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.

Fixes#16517
Given a 3 Server cluster with at least 1 Client connected to Follower 1:
If a NodeMeta.{Apply,Read} for the Client request is received by
Follower 1 with `AllowStale = false` the Follower will forward the
request to the Leader.
The Leader, not being connected to the target Client, will forward the
RPC to Follower 1.
Follower 1, seeing AllowStale=false, will forward the request to the
Leader.
The Leader, not being connected to... well hoppefully you get the
picture: an infinite loop occurs.

Our auth token parsing code trims space around the `Authorization` header but
not around `X-Nomad-Token`. When using the UI, it's easy to accidentally
introduce a leading or trailing space, which results in spurious authentication
errors. Trim the space at the HTTP server.
The job evaluate endpoint creates a new evaluation for the job which is
a write operation. This change modifies the necessary capability from
`read-job` to `submit-job` to better reflect this.

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.
Several `nomad job` subcommands had duplicate or slightly similar logic
for resolving a job ID from a CLI argument prefix, while others did not
have this functionality at all.
This commit pulls the shared logic to the command Meta and updates all
`nomad job` subcommands to use it.

* docs: update version command output

Prior to this change a "Server error" would be returned when ACLs are
enabled which did not match when ACLs are disabled.

The Logfs are a bit weird because they're most useful when converted to
Printfs to make debugging the test much faster, but that makes CI noisy.
In a perfect world Go would expose how many tests are being run and we
could stream output live if there's only 1. For now I left these helpful
lines in as basically glorified comments.
The `nomad fmt -check` command incorrectly writes to file because we didn't
return before writing the file on a diff. Fix this bug and update the command
internals to differentiate between the write-to-file and write-to-stdout code
paths, which are activated by different combinations of options and flags.
The docstring for the `-list` and `-write` flags is also unclear and can be
easily misread to be the opposite of the actual behavior. Clarify this and fix
up the docs to match.
This changeset also refactors the tests quite a bit so as to make the test
outputs clear when something is incorrect.
* Warn when Items key isn't directly accessible
Go template requires that map keys are alphanumeric for direct access
using the dotted reference syntax. This warns users when they create
keys that run afoul of this requirement.
- cli: use regex to detect invalid indentifiers in var keys
- test: fix slash in escape test case
- api: share warning formatting function between API and CLI
- ui: warn if var key has characters other than _, letter, or number

When an auth method was not supplied and the OIDC type was given
in lower case, the CLI was not matching the default method due to
casing and responded with a confusing user message.
This change fixes the above problem, along with making use of the
santized type easier.

Dynamic Node Metadata allows Nomad users, and their jobs, to update Node metadata through an API. Currently Node metadata is only reloaded when a Client agent is restarted.
Includes new UI for editing metadata as well.

This change introduces the Task API: a portable way for tasks to access Nomad's HTTP API. This particular implementation uses a Unix Domain Socket and, unlike the agent's HTTP API, always requires authentication even if ACLs are disabled.
This PR contains the core feature and tests but followup work is required for the following TODO items:
- Docs - might do in a followup since dynamic node metadata / task api / workload id all need to interlink
- Unit tests for auth middleware
- Caching for auth middleware
- Rate limiting on negative lookups for auth middleware
