suites/fs: enable directory fragmentation Setting this in tests globally as a precursor to enabling it by default in the shipping code. Set a low mds bal split size in order to make us hit the fragmentation code more often in than we usually would in a single MDS environment.

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.
