The local cluster starts up Nimbus, which tries to start RockDbStore, which
reads storm.home. So far it's been erroring out, but because Nimbus swallows
the error it hasn't been an issue, apart from the meaningless error logs. I
figure we might as well set storm.home when using a local cluster, since it's
always set in a real daemon, and that's the environment we're trying to
simulate.
