sdong 3ae386eafe Add statistic histogram "rocksdb.sst.read.micros" 
Summary: Measure read latency histogram and put in statistics. Compaction inputs are excluded from it when possible (unfortunately usually no possible as we usually take table reader from table cache.

Test Plan:
Run db_bench and it shows the stats, like:

rocksdb.sst.read.micros statistics Percentiles :=> 50 : 1.238522 95 : 2.529740 99 : 3.912180
