GitLab CI back

[Andrew Bartlett]

G'Day,

A big thank you to everyone for their patience, the GitLab CI private
runners are back now.

There are still things I would like to do:
 - ensure the alternate configuration for really old Samba versions
still works (I think that image ID also changed)
 - decouple the system from the catalyst_samba key and use an ephemeral
key instead
 - provide a top-to-bottom script that pulls a docker image, installs
the required software and runs ansible that only needs the credentials
as input

But for now, it is back, and the bastian host is now running a 2020 set
of updates, which is a good thing regardless. 

Let me know if you have any further problems, otherwise please just
restart the failed jobs.

Finally, I would plea that some other interested team members learn how
all this works, so as to avoid having a single point of failure in
myself.

Thanks!

Andrew Bartlett
