Move packaging metadata into pyproject.toml (again)

This change aims to improve the packaging but requiers Python 3.7.
Python 3.6 as been EOL for a while now but patroni still supports
it and some variants of RH 7 still use it. Therefore, the change
was reverted. But now .. is the time!

-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.
