[kudu-CR] tools: add a tool to summarize data size on a tablet or tablets

["Todd Lipcon (Code Review)" <ge...@cloudera.org>]

Hello Adar Dembo, Will Berkeley, Kudu Jenkins,

I'd like you to reexamine a change.  Please visit

to look at the new patch set (#2).

tools: add a tool to summarize data size on a tablet or tablets

This adds 'kudu local_replica data_size <tablet glob>' which lists the
space usage of a tablet, grouped by type of file, column, rowset, etc.

This would be even more useful in an online context, but it's simpler to
implement offline and still useful for understanding space usage.
