ACCUMULO-378 Utility to just print the replication records repeatedly
ACCUMULO-378 Metadata table has the versioning iterator set at 10.

Someone is a terrible person and set the versioning iterator on the metadata
table to 10 instead of 20 like it is for literally every other table.
ACCUMULO-2574 Change closedTime into createdTime

It's rather impossible to actually konw the exact point in time when
a WAL is no longer in use by any tablets. We can know when a tablet is
done with a WAL, but many tablets may be referencing it which convolutes
things.

Instead, we can get the same intent (global ordering of WALs for a tserver)
by recording the time in which the WAL was first created as this is something
that only occurs once in the lifetime of a file.
