Since the openstack-ci only tests 5 of the many tox enviroments
we had listed and from my knowledge nobody else is testing using
those other non-standard enviroments just reduce the set of applicable
environments to the ones that are being used (which also means we
can remove the usage of toxgen and just stick with a simpler file
that is easier to use, modify and adjust).

Since PBR now supports distinguishing between
a requirements file for py2 and a different requirements
file for py3 we should add the support for that separation
so that it is easier to package taskflow.

To make the README file showup in a more readable manner
on pypi and on other external sites convert the README from
the markdown format and move it to the restructuredtext format
which displays better on those external sites (and keeps our
documentation consistently one format).
