Setting up and maintaining an ElasticSearch cluster is non-trivial. The creators of ElasticSearch, Elasticsearch B.V., sell an Elastic Cloud service, which provides turn-key ElasticSearch clusters ("Hosted deployments"), and it's 30-day trial is helpful for site builders who want to evaluate ElasticSearch, but don't want to spend time setting it up. Elastic Cloud also adds features that are difficult to self-host but desirable for larger organizations (especially Web Crawlers for federated search).
Elastic Cloud Hosted Deployments and the official elasticsearch/elasticsearch library support connecting to an ElasticSearch Server using a Cloud ID and API Key; but ElasticSearch Connector (currently) doesn't expose this connection method by default.
Add an ElasticSearch Connector plugin (similar to the existing BasicAuthConnector and StandardConnector) that allows users to establish a connection to an Elastic Cloud Hosted Deployment acting as a Search API Server by entering a Cloud ID and API key.
Adds a new ElasticSearch Connector type when adding a Search API server with an ElasticSearch backend.
Only API additions.
Hopefully none.

I've added some code in !91; it needs tests; but reviews are welcome.
