to look at the new patch set (#3).

Change subject: Add error handling to KuduBackup
......................................................................

Add error handling to KuduBackup

KuduBackup will attempt to backup every table. If any one table fails the
entire job will fail.

If a table is was already backed up to the specified timestamp or the
table is backed up, the table is marked successful.
If a table fails to back up any partial data will be removed.

At the end of the job if any table has failed to backup/restore an
exception is thrown.

Spark SaveMode overwrite/append semantics are not handled as part of this commit.
