Logging Connector ELK

ELK connector for delivering TWIN log events to an Elasticsearch endpoint for centralised search, dashboards, and alerting.

Entries are converted to Elasticsearch documents and delivered through the bulk API, so a batch costs one HTTP round trip rather than one per entry. Batching is enabled by default. A Logstash HTTP input can be used as the endpoint instead of Elasticsearch. This connector writes entries but does not implement query().
