requirements.txt pinned to legacy versions of libraries

[bar0n36]

Is your feature request related to a problem?

The current version of the Collection requirements file is pinned to old versions of:

• pan-os-python==1.8.0 (Jan '23)
• pan-python==0.17.0 (March '22)
• xmltodict==0.12.0 (Feb 2019)
• panos-upgrade-assurance==0.3.0 (Sept '23)

Describe the solution you'd like

Should this be hard-pinned to these versions, or can it be made to >= versions? Current versions (from pypi) of the python packages are below:

• pan-os-python 1.12.1
• pan-python 0.25.0
• xmltodict 0.13.0
• panos-upgrade-assurance 1.0.1

Describe alternatives you've considered

Fork our own copy of the collection, upgrade and test. Not desirable.
