File src/kudu/util/metrics.h:

PS3:
Since this is a fairly beefy patch to core infrastructure, mind splitting up 
the patch into two?
1. Cleanup only patch with no functional impact.
2. Patch that adds the merging functionality.

PS3, Line 436:   bool merge_by_table = false;
See https://gerrit.cloudera.org/c/13376/2/src/kudu/util/metrics.cc#205: we want 
to keep code in util free of Kudu-specific abstractions like "tables" and 
"tablets". Sounds like you want to merge metrics based on attributes shared by 
their entities; is that right? Perhaps you could structure the new 
functionality in that way?
