Add support authentication with API keys

[andrewkroh]

Elasticsearch has support for authentication with API keys. As a user I would like to be able to configure the elasticsearch output with an API key, as opposed to a username and password, for authenticating.

Logstash would add a header like Authorization: ApiKey base64(<api_key_id>:<key>) to HTTP requests to Elasticsearch.

Any update on this?
*Current workaround is adding Authorization header to custom_headers field.

custom_headers => {
  Authorization => "ApiKey base64(<api_key_id>:<api_key_key>)"
}

Hi, Its fixed but I still need to pass both API_ID and API_KEY value as "<API_ID>:<API_KEY>". It should work directly with base64 encoded API KEY - "BASE64_API_KEY" value only.
