qa: assign prometheus ports during selftest

This was throwing IOError("Port 9283 not free on '::'",)
when trying to serve, since merging https://github.com/ceph/ceph/pull/19744

It's because the standbys (on the same node as the active) are
now trying to listen too.

Fixes: https://tracker.ceph.com/issues/22755

(cherry picked from commit e2c68d5e2582fe610098bc6ea4f0b44ad1df28fd)
