WIP: Add a tool to purge UNDOs, and one to summarize data size
Adds 'local_replica purge_undos', which removes all UNDO data from a
tablet (or set of tablets). This is useful while we don't have automatic
GC of UNDO data, since it seems that UNDOs can take quite a lot of
space.
Adds 'local_replica data_size' which lists the space usage of each of
the blocks in a tablet. This is useful to see where space is going.
This would be useful to have in an online context as well, but having it
offline is helpful to run against existing clusters on older versions.
WIP because this needs a test
