author: Ted Trask (@tdtrask) <ttrask01@yahoo.com>

- This modules allows for enable/disable/activate of C(awall) policies.
- Alpine Wall (C(awall)) generates a firewall configuration from the enabled policy files
and activates the configuration on the system.

description:
- Activate the new firewall rules.
- Can be run with other steps or on its own.
- Idempotency is affected if O(activate=true), as the module will always report a changed state.
