Vladimir Sementsov-Ogievskiy e0f69d83d5 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.
