As of HSEARCH-3239 Open we will need to setup two things for each AWS Elasticsearch endpoint:

• A lockable resource with the appropriate label
• An environment variable with the appropriate name, and the endpoint URL as its value

We could just use the lockable resource name as URL and avoid configuring each endpoint twice. As a bonus, this would allow to configure multiple resources of each type (multiple ES 5.3 clusters for example). Not really useful to us, but a nice bonus nevertheless.
