Some roles now have dependencies on collections, since with ansible-core some of the plugins are now external to ansible and only available via collections.

for background see

The Ansible team regards this as a "not my problem" issue.

I was thinking of adding a non-standard file like `meta/collection-requirements.yml` to the roles that need it - at least we could document that users will have to first do
ansible-galaxy role install
then use
ansible-galaxy collection install -r /path/to/roles/

Any ideas?
