This was a surprisingly involved change. Some of the difficulties included
java.util.Optional purposely not being Serializable (so I had to move a
few Optionals in mapreduce classes to @Nullable) and having to add the Truth
Java8 extension library for assertion support.

This is the first in a series of CLs containing code from an old CL of Dai's that had never been completed, which compares zone data between Datastore and DNS. I had written a script to do this by calling two nomulus commands, but maybe it can be done directly in Java, which would be convenient.
This CL is just the plumbing to check on the status of a Mapreduce. We will need this to know that we can proceed with the next step of comparing the output to the DNS data.
Cloned from CL 134295050 by 'g4 patch'.
