Automatic discovery of packages, py_modules and name (#2894)

It is desirable to have some configurations automatically derived.
This is definitely possible for packages and py_modules, and (based on
these two) also for name.

This change adds a new class `setuptools.discovery.ConfigDiscovery`
implementing the automatic discovery logic for packages, py_modules and
name.
