Support accumulo's new default ssh behavior (#307)

When using the accumulo-cluster script in 2.1.4-snapshot, all
connections now default to being done via ssh vs a local command.

This change modifies the accumulo commands used to ensure that local
start/stop commands are used so that uno's environment variables are
used by accumulo-env.sh
