Amnon Heiman 1f16765140 column family: setting the read and write latency histogram ...

This patch contains the following changes, in the definition of the read
and write latency histogram it removes the mask value, so the the
default value will be used.

To support the gothering of the read latency histogram the query method
cannot be const as it modifies the histogram statistics.

The read statistic is sample based and it should have no real impact on
performance, if there will be an impact, we can always change it in the
future to a lower sampling rate.
