Usage: nomad deployment resume [options] <deployment id>

Resume is used to unpause a paused deployment. Resuming a deployment will

resume the placement of new allocations as part of rolling deployment.

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.
