      Description

      CASSANDRA-2392 saves the index summary to the disk... but when we have saved cache we will still scan through the index to get the data out.

      We might be able to separate this from SSTR.load and let it load the index summary, once all the SST's are loaded we might be able to check the bloomfilter and do a random IO on fewer Index's to populate the KeyCache.
