1. All source job connectors have ZK config hard-coded due to parameter-less MantisSourceJobConnectorFactory. Configuring a MantisClient in this context doesn't make sense, since we can reference the configured HighAvailabilityServices 2. DynamoDBMasterMonitor was erroneuously logging parse errors when reading leadership info from the DB. 3. HighAvailabilityServicesImpl was setting the leader state to NULL, which lead to ResourceClusterGatewayClient constructing an invalid URI. Updating to not update the ResourceClusterGatewayClient when master is NULL.

We were seeing log spam, where a JobSource triggers this code path. It doesn't appear to break anything, but seems a bit weird and leads to log spam. HighAvailabilityServicesUtil logs a few warnings (i.e. "HA service running in local mode. This is only valid in local test."), because this path attempts to "create" the HA services with no properties. I think it is a little weird because I wouldn't expect a job writer to pass Mantis platform configuration for discovering the master, so it seems best to use HighAvailabilityServicesUtil. That is, unless I am missing something...
My understanding is that the HA services should generally be configured if we are here, so should just try to get the reference to HA services.

@Andyz26 - Just a ping... I was also hoping to cut a release after this one. |

I would suggest adding a javadoc here to let user know this will start running the HAService. Also in this case who should be closing the haService if it creates other threads?
