## Description

New Module `avm/res/network/firewall-policy`, migrated from CARML.

## Adding a new module

<!--Run through the checklist if your PR adds a new module.-->

- [x] A proposal has been submitted and approved.
- [ ] I have included "Closes #{module_proposal_issue_number}" in the PR
description.
- [ ] I have run `brm validate` locally to verify the module files.
- [x] I have run deployment tests locally to ensure the module is
deployable.
