Description

storm-elasticsearch has hardcoded configuration for TransportClient, client.transport.sniff = true.

Users may want to change this value, and may also want to add another configuration.
(Please refer https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/transport-client.html)

If we want to pass configurations to TransportClient, I think it would be better to expose Map from EsConfig, and put all things inside Map to ImmutableSettings.settingsBuilder().
