  1. common/options: enable multiple rocksdb compaction threads for filestore 

    One of the major benefits of rocksdb over leveldb is multithreaded
compaction. The default of 1 thread does not provide much benefit, and
is insufficient for heavy rgw workloads.

For high-write and delete omap workloads I've seen up to 8 compaction
threads be used.  There's little overhead to having a higher max than
are needed, so set the default to 8.
