Bugs: AURORA-1493
    https://issues.apache.org/jira/browse/AURORA-1493


Repository: aurora


Description
-------

AURORA-1493: create ELB-friendly endpoint to detect leading scheduler. The fix is to add a
new endpoint - "/leaderhealth" which returns http status code 200 (OK) if the instance is
the leader. If the instance is not the leader but a leading exists, returns 500 (Internal
server error). If there is no leader at all, returns 503 (Service unavailable)
