Palo Alto Tweaks

[tsellers-r7]

Description

This PR tweaks the fields for Palo Alto so as to return better data and/or improve the ability to generate CPEs.

I would have preferred to change PANOS to PAN-OS for the os.product but I wasn't sure what this would break downstream.

I also reset and regenerated the contents of the identifiers/ directory.

Checklist:

• I have updated the documentation accordingly (or changes are not required).
• I have added tests to cover my changes (or new tests are not required).
• All new and existing tests passed.

CC @hdm since I've adjusted some OS values and names.

[hdm]

Thanks! Looks good to me!

Nexpose currently expects PAN-OS for product and family so would be a good change for us at least. Could we add os.family field too? Nexpose checks depend on that field.

FYI @hdm we're going ahead with the switch from PANOS to PAN-OS.
