ec_deployment: Allow users to reset the Elasticsearch password

[marclop]

Overview

To help support cases where the user might have either imported the deployment or changed the password independently, and terraform doesn't have an elasticsearch_password or it's outdated, it would be good to allow users to reset their Elasticsearch password by setting a field boolean field to true.

The endpoint is at /deployments/{deployment_id}/elasticsearch/{ref_id}/_reset-password.

Possible Implementation

Creating a field reset_elasticseach_password of type Bool, where setting the field will reset the Elasticsearch credentials.

This would fix my current situation after I imported an existing deployment.

In my case, after importing deployment, as mentioned in the docs, credentials are empty, but we can workaround this by terraform state pull > state.json, manually add/change credentials, increment serial number and finally terraform state push state.json

Thanks for sharing this workaround, but I think its too "hacky" to be used in general.

IMHO this should be implemented, especially since there is no migration implemented from 0.5.X to 0.6.X
