Modified test cases:
1. osd-backfill-prio.sh:
Set osd_op_queue = wpq for all tests since the mclock doesn't
consider recovery priority as part of its scheduling algorithm.
2. osd-backfill-space.sh:
Set osd_mclock_profile to high_recovery_ops and increase the wait
for backfills timeout to 1200 secs for the following tests:
- TEST_backfill_test_simple()
- TEST_backfill_test_multi()
- TEST_backfill_test_sametarget()
- TEST_backfill_multi_partial()
- TEST_ec_backfill_simple()
- TEST_ec_backfill_multi()
- SKIP_TEST_ec_backfill_multi_partial()
- SKIP_TEST_ec_backfill_multi_partial()
3. osd-backfill-stats:
- TEST_backfill_ec_down_all_out():
Set osd_mclock_profile to high_recovery_ops and increase the wait
for recovery timeout to 240 secs.
