first pass at running rethinkdb from the integration tests instead of build script
Be a bit smarter about finding rethinkdb binary.
Move rethink startup to SetUpFixture
Check path for rethinkdb binary
Use port from app.config for rethinkdb instance
Do not start rethinkdb if something is already running on the configured endpoint
Remove startup from build.sh
Don't try to kill rethink if you didn't start it.
