get rid of weird line breaks and use action (#4926)

* get rid of weird line breaks and use action

When using restarts/stops/starts you'd get weird output sometimes, Strange line breaks 'OK' status overlapping the next lines etc...
This fixes those moves OK to the right place and colorizes them correctly.

* added : for more uniformity

when doing a restart the output looked like:
Stopping Grafana Server ...                                [  OK  ]
Starting Grafana Server: ...                               [  OK  ]

The Stopping line did not have a colon. I added it just to make it look better.
