xfstest: add defragmentation stress tests for ext4
Perform various regression tests for ext4defrag subsystem
301'th Test1: Defragment file while other task does direct AIO
302'th Test2: Perform defragmentation on file under buffered AIO
while third task does direct AIO to donor file
303'th Test3: Two defrag tasks use common donor file.
304'th Test4: Stress defragmentation. Several threads perform
fragmentation at random position use inplace=1 will
allocate and free blocks inside defrag event improve
load pressure.
This tests are considered dangerous because 302'th and 303'th are known
to trigger OOPS on recent kernels
