Support opensearch

[amirkkn]

I'm trying to use this terraform provider for provisioning opensearch roles and other configs, which was deployed on top of the kubernetes using official helm chart. I don't use the AWS opensearch.

Terraform detects my elasticsearch cluster and the connection is established successfully, but I get the error during terraform apply:

Error: ElasticSearch version 1.2.3 is older than 6.0.0 and is not supported.

Is any plan to support opensearch in the near future?

Thanks in Advance

Opensearch helm chart: 1.5.7
Opensearch app version: 1.2.3
Terraform elasticsearch provider version: 2.0.0-beta.2

Please see #218, enabling compatibility mode on the cluster before using the provider should enable almost all features immediately.
