PR #14492 introduced a new check to return 0 when the `nomad job plan`
command returns a diff of type `None`.
But the `-diff` CLI flag was also being used to control whether the plan
request should return the diff of not instead of just controlling if the
diff was printed.
This means that when `-diff=false` is set the response does not include
any diff information, and so the new check panics.
This commit fixes the problem by always requesting a diff and using the
`-diff` only for controlling output, as it's currently documented.
* Upgrade from hashicorp/go-msgpack v1.1.5 to v2.1.0
Fixes#16808
* Update hashicorp/net-rpc-msgpackrpc to v2 to match go-msgpack
* deps: use go-msgpack v2.0.0
go-msgpack v2.1.0 includes some code changes that we will need to
investigate furthere to assess its impact on Nomad, so keeping this
dependency on v2.0.0 for now since it's no-op.

Adds a new configuration to clients to optionally allow them to drain their
workloads on shutdown. The client sends the `Node.UpdateDrain` RPC targeting
itself and then monitors the drain state as seen by the server until the drain
is complete or the deadline expires. If it loses connection with the server, it
will monitor local client status instead to ensure allocations are stopped
before exiting.
* api: enable support for setting original source alongside job
This PR adds support for setting job source material along with
the registration of a job.
This includes a new HTTP endpoint and a new RPC endpoint for
making queries for the original source of a job. The
HTTP endpoint is /v1/job/<id>/submission?version=<version> and
the RPC method is Job.GetJobSubmission.
The job source (if submitted, and doing so is always optional), is
stored in the job_submission memdb table, separately from the
actual job. This way we do not incur overhead of reading the large
string field throughout normal job operations.
The server config now includes job_max_source_size for configuring
the maximum size the job source may be, before the server simply
drops the source material. This should help prevent Bad Things from
happening when huge jobs are submitted. If the value is set to 0,
all job source material will be dropped.
* api: avoid writing var content to disk for parsing
* api: move submission validation into RPC layer
* api: return an error if updating a job submission without namespace or job id
* api: be exact about the job index we associate a submission with (modify)
* api: reword api docs scheduling
* api: prune all but the last 6 job submissions
* api: protect against nil job submission in job validation
* api: set max job source size in test server
* api: fixups from pr
Nomad's security model requires mTLS in order to secure client-to-server and
server-to-server communications. Configuring ACLs alone is not enough. Loudly
warn the user if mTLS is not configured in non-dev modes.
These endpoints all refer to JobID by the time you get to the RPC request
layer, but the HTTP handler functions call the field JobName, which is a different
field (... though often with the same value).
This update changes the behaviour when following logs from an
allocation, so that both stdout and stderr files streamed when the
operator supplies the follow flag. The previous behaviour is held
when all other flags and situations are provided.

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.

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.
