qa/tests: fix test_list_enabled_modules timeout error

This test deals with enabling/disabling the modules. The assumption I
have is after enabling the
module test will wait for an active mgr but its not able to find it in
time and it fails. so taking inspiration from https://github.com/ceph/ceph/pull/58995/commits/6c7253be6f6fbfa6faed7a539cb78847fec04580 adding retries and logs to see if that's the case
