All arguments to this function (except panorama_error, firewall_error,

The `vsys`, `device_group`, `vsys_dg`, `vsys_importable`, `rulebase`,
`template`, and `template_stack` params can be any of the following types:
* None - do not include this in the spec
* True - use the default param name
* string - use this string for the param name
The `min_pandevice_version` and `min_panos_version` args expect a 3 element
tuple of ints. For example, `(0, 6, 0)` or `(8, 1, 0)`.
If you are including template support (by defining either `template` and/or
`template_stack`), and the thing the module is enabling the management of is
an "importable", you should define either `vsys_importable` (whose default
value is None) or `vsys` (whose default value is 'vsys1').
Arguments:
vsys: Firewall only - The vsys.
device_group: Panorama only - The device group.
vsys: The vsys (default: 'vsys1').
device_group: Panorama only - The device group (default: 'shared').
vsys_dg: The param name if vsys and device_group are a shared param.
vsys_importable: Either this or `vsys` should be specified. For:
