[Enhancement]: aws_elasticache_replication_group auth_strategy

[as-herzog]

Description

Attempting to migrate from Redis AUTH to RBAC by removing auth_token and adding user_group_ids. This is resulting in an error:

Error: updating ElastiCache Replication Group <group>: InvalidParameterCombination: User group can't be associated with auth token enabled. Pass AuthStrategy delete to proceed.

Being able to pass an auth_token_auth_strategy of DELETE instead of hardcoding ROTATE would seemingly open up the ability for this switch. Could default to rotate and no-op if auth_token not set?

Affected Resource(s) and/or Data Source(s)

• aws_elasticache_replication_group

Potential Terraform Configuration

resource "aws_elasticache_replication_group" "default" {
   engine_version = "6.x"
   replication_group_id = "some_id"
   auth_token_auth_stragey = "delete"
   user_group_ids = ["some_id"]
}
