Support a Edge policy and Custom Response Headers on backend buckets

[LeonardoDG2084]

Hi,
I'm using this module (https://github.com/terraform-google-modules/terraform-google-lb-http/tree/main/modules/backend) and I noticed that the google_compute_backend_bucket resource doesn't support some attributes like edge_security_policy and custom_response_headers which are implemented in the google_compute_backend_service resource by this module. Is this lack of implementation a design decision (best practice), or has it really not been implemented?
