ci: move system tests from Github Actions to Testing Farm

[pbrezina]

The system tests can quickly deplete available Github runners (20)
and we need them for process purposes (Accepted label). So we keep
only quick checks in GHA now.

Testing Farm is supported infrastructure for Fedora Project, we should
be able to see infra issues resolved more quickly as we can actually
ping people when needed.

This is waiting for new feature in packit:

• Document the skip_install test job option packit/packit.dev#1174
• feat: honor skip_install by not installing Copr artifacts in Testing Farm packit/packit-service#3190
• feat: add skip_install option for test jobs packit/packit#2776

And SSSD/sssd-ci-containers#219

[pbrezina]

Note: Do not forget to switch sssd-ci-containers repo in the test plan after SSSD/sssd-ci-containers#219 is merged.

I get this failure on centos-10... it is a segfault in autofs, I can't reproduce this locally so I'm trying to catch it in reserved TF run.

FAILED tests/test_autofs.py::test_autofs__new_map_entries_added_to_provider_are_visible_after_reload (ldap) - pytest_mh.conn.ssh.SSHProcessTimeoutError:

Other two errors are in provisioning phase. Both looks like a network error.

On TF side, reported, they will implement a retry

Other one gets further but fails when downloading containers. I implemented a retry on our side.
