Fixes a few minor issues (apache#282)

Ran into a few problems when trying to run a small 2.1.4-SNAPSHOT
cluster.  Fixed the following problems.

 * When build in accumulo-testing use the version of accumulo on the
   cluster.
 * Update the cluster yaml file to align with the latest changes in
   2.1.3.
 * Handle a property that was recently deprecated in 3.1.0-SNAPSHOT.
 * Fix an issue with empty continuous ingest table config.
