AWS ES terraform does not have "http-compression" in config aws_elasticsearch_domain

Hi Team,

I am trying to enable gzip compression on AWS ES. Currently running ES 6.8 (ES 7+ has this by default) . https://docs.aws.amazon.com/elasticsearch-service/latest/developerguide/gzip.html . I am able to do this using cURL for testing purpose but I wanted to ship this change via terraform. Required documentation seems to have majority of keywords which we are using. But my question is does anyone know the keyword/syntax for enabling “http_compression” ? Because this https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/elasticsearch_domain clearly does not have that information.
