CEKit Incompatibility with Packaging 22.0

[lampajr]

Describe the bug

Cekit tool seems to be incompatible with newer 22.x version of packaging.

Running cekit with packaging version 22.x keep throwing the following error:

    from packaging.version import LegacyVersion
ImportError: cannot import name 'LegacyVersion' from 'packaging.version' (/home/alampare/miniconda3/envs/cekit-4.4/lib/python3.10/site-packages/packaging/version.py)

This incompatibility was introduced with new 22.0 version of packaging [1] due to:

Remove LegacySpecifier and LegacyVersion (issue:`407`)

[1] https://github.com/pypa/packaging/blob/main/CHANGELOG.rst#220---2022-12-07

To reproduce

Install latest version of packaging:

pip install packaging==22.0

Run cekit command, for instance:

cekit --verbose --redhat build docker

Expected behavior
The command should work and the build should start.
