qa/tasks/mgr/test_progress: fix wait_until_equal

Octopus ceph_test_case doesn't have period arg
so remove that in wait_until_equal. Also increase
time to wait for complete events by using RECOVERY_PERIOD
instead of EVENT_CREATION_PERIOD

Not needed in masters because only octopus and nautilus
doesn't have a period argument in qa/tasks/mgr/test_progress.py
wait_until_equals() function
