Description

Need tablet max and average size metric per table in order to be able to alert on the scenarios, where one tablet is much larger that the other ones, for a long period of time.

Contributor guide

Research direction
Examine the existing metrics collection in the DocDB tablet server, identify where tablet size data is available, and follow the pattern of existing metrics to expose max and average size per table.
