De-quarantine test test_pause_unpause_vm in common templates dirs

 
Issue is sporadic failures during `wait_for_pause_status` step, which performs 2 checks to verify VM got into paused state:

1. check virsh domstate via virt-launcher pod, which is a very old W/A for BZ bug (also requires VM to have admin_client to pause/unpause because only admin user can execute commands on virt-launcher pods)
2. check VMI conditions

Fix will be:

1. in python wrapper: drop domstate check from pause/unpause calls (not needed anymore as checking for VMI condition is sufficient)
2. in cnv-tests: drop admin client from `pause_optional_migrate_unpause_and_check_connectivity`
