Add spec file

[daaitudian]

Hi,
I added a spec file to help rpm build.

@daaitudian Can you please give me some hints regarding how to build locally using this spec.in file? On linter repo I only use a spec file and build using packit build locally.

Hi @ssbarnea :

Here is a brief explanation,

1. Fill in "Version", "Release" and "%Changelog" in the spec.in file according to the actual information

2. Pack the source code into the style required by "Source0" then copy it to the Source folder. copy the rpm/python-ansible-compat.spec.in to the SPECS folder, and rename it to python-ansible-compat.spec

3. Use the “rpmbuild” command to perform the rpm build

Do I need to write a detailed README ?

@daaitudian Please take a look at #291 which we will merge soon. It is based on the setup we already have for ansible-lint and we use packit to test rpm building, which is basically essential for knowing that the spec is valid.

Still, I know that my PR does not update the changelog, so I will be more than happy if you could make one or two follow-ups to improve it.

The reason why I did not took you change was because I was not able to test it, especially on proposed PRs. There is no need to add documentation if we can ensure that the testing happens on CI -- I would call this self-documented ;)

@ssbarnea Thanks a lot for your help and modification. I will follow up on it later.
