@leelavg and I have discussed the version scheme and since we are not expecting frequent maintenance release versions, agreed with use date scheme.

@tomswallaRH this will require update on the version:
https://github.com/RedHatQE/pylero/blob/main/setup.py#L29

also with
https://github.com/RedHatQE/pylero/blob/main/.github/workflows/publish-to-pypi.yml

in position, when we use tag and release package on github new pypi will be published, so tag also need be the date format.

Hi, @simzacks there are a few types of versioning. Which do you think would suit this project best?
