Feature: Panorama - Support the use of HA Device Priority setting and the use of PAN-OS Variables in Group ID setting

[MaHusch]

Is your feature request related to a problem?

I often configure one template for all firewalls with the HA settings and use PAN-OS variables for the Group ID, IP addresses and device priority.
Since I create this template in almost every new Palo Alto Panorama environmnet, I want to automate this using ansible. While doing so, I saw two imperfactions:

1. I cannot use the Device Priority setting at all using the "panos_ha" module.
2. The value for "ha_group_id" can only be an integer, but I need a string since I want to use a PAN-OS variable.

Describe the solution you'd like

I would like to have the option to set the Device Priority via the Ansible module "panos_ha". Also, it would be nice to have the option to set a string for the "ha_group_id" value, so that I can use PAN-OS variables for the value.

Describe alternatives you've considered

Since this is a minor issue for me, I can simply set these two things myself in the UI.
