cephfs: test fragment size limit
The fragment configuration uses 10000 for the fragment max size. The reason for
this is that many tests add 1000 files to a single directory which will hit
this limit without fragmentation catching up.

The test_dirfrag_limit test confirms:

o That the directory fragment size cannot exceed mds_bal_fragment_size_max (using a limit of 50 in all configurations).
o That fragmentation (forced) will allow more entries to be created.
o That unlink fails when the stray directory fragment becomes too large and that unlinking may continue once those strays are purged.
