Start, Stop Worker from CLi in Linux

[fractalnode]

I would like to be able to start and stop single worker from commandline in Linux
e.g

• cli.py run (ALL)
• cli.py run worker1
• cli.py run worker1 worker2
• ##############################
• cli.py stop (ALL)
• cli.py stop worker1
• cli.py stop worker1 worker2

Postponed until cli refactor along with other cli improvements

@PermieBTS @MarkoPaasila Do we have any cli configuration packages that were previously considered and evaluated? I recall it was discussed. Curating a list of what you'd like here would help facilitate the process of replacing Whiptail. Whiptail is not well maintained and limited in functionality.

Good idea, I like it, should be considered when splitting core and frontends.
