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.

The workflow described in the docs for apt installation is deprecated. Update to
match the workflow described in the Tutorials and official packaging guide.
The `docker` driver cannot expand capabilities beyond the default set when the
task is a non-root user. Clarify this in the documentation of `allow_caps` and
update the `cap_add` and `cap_drop` to match the `exec` driver, which has more
clear language overall.
When cluster administrators restore from Raft snapshot, they also need to ensure the
keyring is in place. For on-prem users doing in-place upgrades this is less of a
concern but for typical cloud workflows where the whole host is replaced, it's
an important warning (at least until #14852 has been implemented).
The configuration docs for `client.template.vault_retry`, `consul_retry`, and
`nomad_retry` incorrectly document the default number of attempts to be
unlimited (0). When we added these config blocks, we defaulted the fields to
`nil` for backwards compatibility, which causes them to fall back to the default
consul-template configuration values.
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.

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.
ACL policies can be associated with a job so that the job's Workload Identity
can have expanded access to other policy objects, including other
variables. Policies set on the variables the job automatically has access to
were ignored, but this includes policies with `deny` capabilities.
Additionally, when resolving claims for a workload identity without any attached
policies, the `ResolveClaims` method returned a `nil` ACL object, which is
treated similarly to a management token. While this was safe in Nomad 1.4.x,
when the workload identity token was exposed to the task via the `identity`
block, this allows a user with `submit-job` capabilities to escalate their
privileges.
We originally implemented automatic workload access to Variables as a separate
code path in the Variables RPC endpoint so that we don't have to generate
on-the-fly policies that blow up the ACL policy cache. This is fairly brittle
but also the behavior around wildcard paths in policies different from the rest
of our ACL polices, which is hard to reason about.
Add an `ACLClaim` parameter to the `AllowVariableOperation` method so that we
can push all this logic into the `acl` package and the behavior can be
consistent. This will allow a `deny` policy to override automatic access (and
probably speed up checks of non-automatic variable access).

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.
* client: disable running artifact downloader as nobody
This PR reverts a change from Nomad 1.5 where artifact downloads were
executed as the nobody user on Linux systems. This was done as an attempt
to improve the security model of artifact downloading where third party
tools such as git or mercurial would be run as the root user with all
the security implications thereof.
However, doing so conflicts with Nomad's own advice for securing the
Client data directory - which when setup with the recommended directory
permissions structure prevents artifact downloads from working as intended.
Artifact downloads are at least still now executed as a child process of
the Nomad agent, and on modern Linux systems make use of the kernel Landlock
feature for limiting filesystem access of the child process.

* docs: update version command output
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.
