[!73] [CI] Explicitly include the variables: in the yaml anchor merge.

Merge branch 'yaml-achors-explicit-recursive-merge' into 'master'

Merging in a yaml anchor into a substructure is not recursive, later
definitions in that substrucure will override instead of add to the
definitions from the anchor. So do include the base definitions explicitly.
This is mainly a problem with the variables: section in job definitions.

Closes: [#33]
