upstream CI: Add support for testing ansible-freeipa as a collection.

Provide a pipeline to test ansible-freeipa as an Ansible Galaxy
collection. The tests will use 'utils/build-galaxy-release.sh' to
create the galaxy release file, install it as a collection, and run
the tests in it, which were modified to use FQCN.

The tests will run only on 'fedora-latest' for each PR, and on all
platforms for nightly and weekly tests.
