Deploy list of OPIs repositories

See merge request ics-ansible-galaxy/ics-ans-role-phoebus!2

To match the recently agreed upon terminology alignment

ess-opis is special and is mounted under /ess-opis in CS-Studio.
For compatibility, it's better to keep it under the same path and
separated from the new list of repos.
Would allow to mount the new list of repos under another mount point.

JIRA INFRA-2105 #action In Progress

to have separate environments).
And Phoebus is still CS-Studio (just a new version).

JIRA INFRA-1428 #action In Progress

The script needs more modifications to set the variables required for
the local Python environment.
We don't really have to use the phoebus.sh script that comes with the
release (it doesn't contain much).

Allow to start phoebus from the command line as well.
