Allow to retrieve root applications from API

[dersoi]

There is a feature missing from the PANOS API. While you can easily retrieve all applications and all applications group, you cannot retrieve root applications.

This means that if you want to check if "Jira" is a valid application, you 'd think you can't because you would only be able to retrieve :

• jira-base
• jira-downloading
• jira-editing
• jira-posting
• jira-uploading

But Jira is a valid application, which contains all 5 above-mentioned applications.

Should be able to get the container app from the Predefined object instantiated in a PanDevice

from panos.firewall import Firewall

fw = Firewall( .... )
fw.predefined.refreshall_applications()
fw.predefined.application_container_objects['jira'].applications

Worth noting that that is just a list of strings of the names though. To get the object properties of each you'd need to grab them with the application method of the Predefined object.

# Not sure if this is the easiest/best way to do this, but it does work
for app in fw.predefined.application_container_objects['jira'].applications:
    fw.predefined.application(app)

This only gives me the applications mentioned above, but not "jira"...
