qa: enable thrasher for MDS cluster size (vary max_mds)
Added by John Spray about 9 years ago.
Updated about 5 years ago.
Description
Rather than just killing MDSs within a fixed size cluster, have a thrasher that varies max_mds and deactivates MDSs to control the size of the cluster. This will exercise the stopping/creating states while under load.
NB while adding cluster size tests, also check the mon commands e.g. #10862 (don't allow deactivate rank 0)
