- everytime for develop branch commits or tags
- on manual trigger for other branches
- only for the "dmc" repository workspace. Pipelines outside "dmc"
  workspace (such as forks or merge requests) have no chance of
  succeeding the publish job

CI: Remove the "publish-production" publish job. This has been moved to the "fts/build-utils" repository

Flavour labels were removed from globus library names in 2010.

CXX is the standard variable for this purpose.
CPP is usually used to indicate the C preprocessor.

- CC7 build jobs do not properly identify that the commit matches a tag
- Centos8 and Fedora jobs always identify when the commit matches a tag
- Gitlab-CI may run both a commit and a tag pipeline for the same commit. This creates the unwanted behavior of Centos8 and Fedora building a tag RPM in a commit pipeline

In the end, pass the branch variable from the pipeline to the build script, which now accepts a regex to identify tags

- Add print info function to build script
- Minor fixes to repo manager script

  - Build jobs for Fedora 33, Fedora 34 and Fedora Rawhide
  - Avoid failing the publish job if Fedora Rawhide RPMs do not exist
  - The "gfal2-repo-manager" script should recognize Fedora 35 and 36 as Rawhide versions
