pause, resume and abort running builds cmd (#421)

- Feature: `zen builds pause`, `zen builds resume` and `zen builds abort` commands to control a running `zen builds` command
  - `--process-id` the process id to control, if omitted it tries to find a running process using the same executable as itself
- Improvement: Process report now indicates if it is pausing or aborting
