Add support for "Apply to New App-IDs only" parameter in panos.objects.ApplicationFilter class

Is your feature request related to a problem?

panos.objects.ApplicationFilter does not have a paramater to include "Apply to New App-IDs only".

Describe the solution you'd like

Add a parameter "apply_to_new_app_ids_only" (bool) to the class panos.objects.ApplicationFilter.

Describe alternatives you've considered

There are no real alternatives other than manual creation of such filters, or the use of XML API directly.

Additional context

We have a whole security policy built using the SDK (with the exception of Security Profiles that are also missing from the SDK) and would like to introduce application filters and policy rules for new AppIDs to follow the Palo's BPA for content updates (https://docs.paloaltonetworks.com/pan-os/10-2/pan-os-upgrade/software-and-content-updates/best-practices-for-app-and-threat-content-updates/best-practices-mission-critical#id184AH00L078)

Start with the panos.objects.ApplicationFilter class and trace how its parameters are represented in the PAN-OS SDK. Add support for the requested apply_to_new_app_ids_only parameter, then verify that an ApplicationFilter can represent and serialize the setting correctly.
