mgr/test_progress.py: Delay recover in test_progress

Changes some the tests in teuthology to make
the test more deterministic.
Using:

`ceph osd set norecover` and
`ceph osd set nobackfill` when marking osds in
or out. As this will delay the recovery and make
sure it the test cases get the chance to check
that there is actually events poping up in
the progress module.

took out test_osd_cannot_recover from
tasks/mgr/test_progress.py since it is no longer
a relevant test case since recovery will get
triggered regardless if pg is unmoved.

Ignoring `OSDMAP_FLAGS` in teuthology
because we are using norecover and nobackfill
to delay the recovery process, therefore, it
will create a health warning and fails the
teuthology test.
