Introduce package metadata configuration by using setup.cfg

Since setuptools 30.3.0 we can use setup.cfg to configure package
for build and distribute. These changes propose to adopt a more
modern approach to package pymemcache by using latest and stable
feature of setuptools.

Overview:
- remove python code to maintain
- introduce package metadata,
- centralize version management in package metadata
