Describe the changes you're proposing

Manage Firewalld policies.

A new feature, policy objects, will be part of the firewalld feature release (v0.9.0). This is a major feature that has been in the works for almost a full year. It is significant because it closes one of the long standing gaps in firewalld’s functionality: forward and output filtering.

This feature looks nice. Thank you for implementing this. Do you think you would be able to ad some inspec tests for the policy module to the right files in https://github.com/saltstack-formulas/firewalld-formula/tree/master/test/integration/default/files/_mapdata? That would give us a bit of testing coverage for your change.
