Description

min/max/mean of row size in columns and bytes would be useful to expose via jmx (don't worry about nodetool for now)

it is tempting to expose an SSTableMBean but I don't really want to get into dynamically un-registering those when they get compacted. So let's just expose each metric as a List<Long> in CFSMBean
