METRON-439: Stellar : IS_EMPTY(host) throws exception Fix Stellar IS_EMPTY validation to handle empty and null Addresses https://issues.apache.org/jira/browse/METRON-439 Things have changed a bit since the original Jira was filed. Most notably, this error appears while dumping config from Zookeeper after it has already been loaded. The current functionality/validation would not have allowed the load to succeed in the first place. Even so, empty and null checks could be handled more gracefully. This PR changes IS_EMPTY to return true on null or empty string rather than throw an exception. Added new unit tests and validated on quick-dev with multiple bro messages - normal host, empty host string, and null/non-existent host string.
