atf-python(3): add atf-python introduction for atf test library.

[Rin0913]

I wish I could write a good documentation, but what I have done is not so good.

Please provide some advises if possible.

Documentation! Great, thank you!

There are a couple examples under tests/examples that can be pointed out in this man page.

[Rin0913]

@jlduran Added!

@lwhsu Please assign reviewers, thanks.

Please address the issues reported by:

mandoc -T lint tests/atf_python/atf-python.3

[Rin0913]

@jlduran Done.

[jlduran]

Thank you. This is very nice to have. Should a reference to this man page be in atf(7)? LGTM.

A reference has been added to atf(7).

I have no relation to atf-python implementation to help in cases if something is missing or a special moment should be mentioned. Nevertheless, the foundation has been laid and future improvements have the baseline. Thank you for the improvement!

It has been a week since your approval.

If there is no one who wants to review, maybe we could merge the commits now?

Thank you very much.

It has also been reviewed by @ihoro, but I should not commit without explicit approval. cc/ @bsdimp @emaste

@lwhsu Done.

i would like to land this but i'm not clear what is still required. it looks like tests/atf_python/atf-python.3 was already committed, is it only the Xr in atf.7 which is still pending?
