* Support for masquerade settings
Ability to enable and disable masquerade settings from ansible via:
- firewalld: mapping=masquerade state=disabled permanent=true zone=dmz
Placeholder added (mapping) to support masquerade and port_forward
choices initially - port_forward not implemented yet.
* Permanent and Immediate zone handling differentiated
* Corrected naming abstraction for masquerading functionality
Removed mapping tag with port_forward choices - not applicable!
* Added version info for new masquerade option
Pull Request #2017 failing due to missing version info
