Change subject: Disable RESTBase highest max SSTables per read threshold
......................................................................
Disable RESTBase highest max SSTables per read threshold
With instance sizes in-flux, and expansions taking place, it is proving
difficult to provide meaningful thresholds that are entirely immune from
false positives. Hopefully we can re-enable this in the near future when
things have settled a bit, (or if an alternative form of alerting can be
found).
