Archive Pagure repository and redirect to GitLab
This commit removes all files in the repository that are now hosted in
other git repositories. It also adds clear information about next steps
in this Pagure repository.
To conclude the GitLab migration, we will achieve zero open issues on
the Mindshare Pagure repo and then set it to read-only status. Any new
issues should be closed and manually copied to GitLab by a Committee
Part of #370.
