Use install_requires in setup.py

Using install_requires makes sure that if some code is using Swift internal
and wants to require Swift, all its dependencies have been already pulled.
This is really useful on test automation for example, otherwise, code might
be failing because on of the module listed in pip-requires is not instaled.

Also, we change the pip-requires files to use >= rather than ==, so the
requirements are easily fulfiled with distribution provided packages.
