Cleanup and consolidate the CI yaml docs (!17595) · Merge requests · GitLab.org / GitLab FOSS · GitLab

Achilleas Pipinellis - OOO until November 25th (parental leave) requested to merge docs/ci-yaml-cleanup into master Mar 07, 2018

What does this MR do?

I started adding some missing info in the CI yaml docs, but I git carried away and cleaned it up :)

Are there points in the code the reviewer needs to double check?

Some links where changed, the lint passes, but there might some a possibility I forgot to change the anchor links some place :)

Once this is approved I'll provide an EE MR, since there will probably be conflicts.

Why was this MR needed?

General cleanup.

What are the relevant issue numbers?
