Sync swiclops fork to current HEAD

[Michael-Hollister]

Before merging swiclops updates for Traefik support, the swiclops branch needs to be rebased. Feel free to merge this PR or rebase/sync the fork yourself to close the issue.

I cannot resolve conflicts in the swiclops branch, but in case you wish to merge this PR, you can choose the master set of changes to resolve conflicts in group_vars/matrix_servers (choose ([{'name': (devture_traefik_certs_dumper_identifier + '.service'), 'priority': 300, 'groups': ['matrix', 'traefik-certs-dumper']}] if devture_traefik_certs_dumper_enabled else [])) .
