The alloc exec and filesystem/logs commands allow passing the `-job` flag to
select a random allocation. If the namespace for the command is set to `*`, the
RPC handler doesn't handle this correctly as it's expecting to query for a
specific job. Most commands handle this ambiguity by first verifying that only a
single object of the type in question exists (ex. a single node or job).
Update these commands so that when the `-job` flag is set we first verify
there's a single job that matches. This also allows us to extend the
functionality to allow for the `-job` flag to support prefix matching.
Fixes: #12097
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.

Alloc exec only works when task is passed as a flag and not an arg.
Alloc logs currently accepts either, but alloc signal and restart only
accept task as an arg. This adds -task as a flag to the other alloc
commands to make the cli UX consistent. If task is passed as a flag and
an arg, it ignores the arg.
The `nomad alloc logs` command does not remove terminal escape sequences for
color from the log outputs of a task. Clarify that the standard `-no-color`
flag, which does apply to Nomad's error responses from `nomad alloc logs`,
does not apply to the log output.
