Migrate setup.py to pyproject.toml

[Kenin Kujovic]

What happened?

Like packaging.python.org says

A pyproject.toml file is strongly recommended. The presence of a pyproject.toml file itself does not bring much. [1] What is actually strongly recommended is the [build-system] table in pyproject.toml.

How can we reproduce it (as minimally and precisely as possible)?

Nothing to reproduce

What did you expect to happen?

Nothing expected

Patroni/PostgreSQL/DCS version

• Patroni version:
• PostgreSQL version:
• DCS (and its version):

Patroni configuration file

No conf file

patronictl show-config

No config

Patroni log files

No logs

PostgreSQL log files

No logs

Have you tried to use GitHub issue search?

• Yes

Anything else we need to know?

Here's a migration I've done pretty quickly(not tested). Do not forget to include non python files if exists. Hope I could help.

If it doesn't bring much, what is the point in adding it?
Actually, it will bring some inconveniences, because we will have to maintain list of dependencies in multiple places...
