Revert_d39122d (move packaging to pyproject.toml)

This changes requiered python 3.7 which I overlooked at first. I would
like to be able to install the check any patroni server and Patroni
supports python 3.6.

+check_patroni works on python 3.6, we keep it that way because patroni also
+supports it and there are still lots of RH 7 variants around. That being said
+python 3.6 has been EOL for age and there is no support for it in the github
+CI.
