Subject: [PATCH] API: Adding read, write latency histogram to column_family

This adds the latency histogram to the column_family swagger
definitions.
The definitions are based on the ColumnFamilyMetrics.
It adds the following commands:

get_read_latency_histogram
get_all_read_latency_histogram
get_write_latency_histogram
get_all_write_latency_histogram
