iotests/151: Test that active mirror progresses

Before this series, a mirror job in write-blocking mode would pause
issuing background requests while active requests are in flight. Thus,
if the source is constantly in use by active requests, no actual
progress can be made.

This series should have fixed that, making the mirror job issue
background requests even while active requests are in flight.

Have a new test case in 151 verify this.

iotest 151: add test-case that shows active mirror dead-lock

There is a dead-lock in active mirror: when we have parallel
intersecting requests (note that non intersecting requests may be
considered intersecting after aligning to mirror granularity), it may
happen that request A waits request B in mirror_wait_on_conflicts() and
request B waits for A.

Look at the test for details. Test now dead-locks, that's why it's
disabled. Next commit will fix mirror and enable the test.
