module: gcp_compute_firewall
description:
- Each network has its own firewall controlling access to and from the instances.
- All traffic to instances, even from other instances, is blocked by the firewall
  unless firewall rules are created to allow it.
- The default network has automatically created firewall rules that are shown in default
  firewall rules. No manually created network has automatically created firewall rules
  except for a default "allow" rule for outgoing traffic and a default "deny" for
  incoming traffic. For all networks except the default network, you must create any
  firewall rules you need.

- For authentication, you can set service_account_email using the C(GCP_SERVICE_ACCOUNT_EMAIL)
  env variable.
- For authentication, you can set auth_kind using the C(GCP_AUTH_KIND) env variable.
- For authentication, you can set scopes using the C(GCP_SCOPES) env variable.
