[UPDATE] Allow Direction selection and priority config for GCP firewall

[JamalSky]

Allow GCP firewall rules to be built with the direction parameter and the priority config. https://docs.ansible.com/ansible/latest/collections/google/cloud/gcp_compute_firewall_module.html#parameter-direction This allows us to set EGRESS or INGRESS. Default will be INGRESS.

https://docs.ansible.com/ansible/latest/collections/google/cloud/gcp_compute_firewall_module.html#parameter-priority This allows us to set priority. Default will be 1000.
