Update monitor func not to take a prefix (#9251)
The only user of monitor(evalID, true) was command/eval_status, and
eval_status had a duplicate of the prefix-handling code inside it, so in
all cases the complete evalID was being passed to monitor.

Given that, we can remove the prefix code from command/monitor, and
remove the boolean arg.

Resume is used to unpause a paused deployment. Resuming a deployment will
resume the placement of new allocations as part of rolling deployment.

-detach
Return immediately instead of entering monitor mode. After deployment
resume, the evaluation ID will be printed to the screen, which can be used
to examine the evaluation using the eval-status command.
