 ### Enhancements

 ### Bugfixes
 
 * [#188](https://github.com/Icinga/icinga-powershell-framework/pull/188) Removes hardcoded zones `director-global` and `global-zones` which were always set regardless of user specification. This fix will ensure the user has the option to add or not add these zones
