Not able to use API Keys from Elastic Cloud #454
Description
We're running Elasticsearch on Elastic Cloud and they don't allow Basic Auth as authentication method.
You can only use API Keys.
Unfortunately I can't find a way to use this Elasticsearch exporter with API Keys. I tried to include the id and key as username and password in the URI in different ways, but Elasticsearch doesn't accept that.
Is there a way to use an API key as authentication method?
