Title: Add some basic checking in startCassandra|stopCassandra

1) Wait a little bit after starting cassandra.
Maybe this process fails. In this case one can report a problem.
2) Make sudo don't ask for password. Nobody's listening for that.
3) Log sudo process output in case of a failure

This improvement is inspired by my experience of deploying Priam.
It is very easy to forget that tomcat has no permission to start|stop cassandra.
And there aren't any errors in logs in this case.
