Adam Williamson 94b47afc53 Tweak setup_tap_static and FreeIPA tests for resolved
This does some of the things suggested by cheimes in
https://bugzilla.redhat.com/show_bug.cgi?id=1880628#c24 . It
seems to make the replica tests work with resolved, still work
with pre-F33 resolving, and not break anything. Also remove the
workaround to disable resolved if it's running, as we can now
work with it.
