Fix breaking change introduced in 0.46.0 - `user_group_ids` conflicts…

… with auth_token

why

• If you specify only auth_token - Terraform plan will fail because it interprets user_group_ids = [] as specified value

Before 0.46.0 I can do next:

module "redis" {
  source  = "cloudposse/elasticache-redis/aws"
  version = "0.45.0"

  auth_token         = join("", random_password.auth_token[*].result)
}

After upgrade I need to do next, which I don't like:

module "redis" {
  source  = "cloudposse/elasticache-redis/aws"
  version = "0.48.0"

  # Confilicting parameters. Could be set only one of them
  auth_token         = join("", random_password.auth_token[*].result)
  user_group_ids     = null
}

So I just return previous logic

module "redis" {
  source = "git::https://github.com/MaxymVlasov/terraform-aws-elasticache-redis?ref=83f0142d97123157482d05c62eaaeecbacfb71e1"

  auth_token         = join("", random_password.auth_token[*].result)
}
