[Pulp-list] dropping el6 builds of Pulp

Thanks everyone for your feedback, and please keep it coming if there is

It sounds like the general sentiment here and elsewhere is that the end to
making el6 RPMs should be planned and well-defined, which leans us toward
making 2.11 the last Y release to have el6 RPMs, and providing them for all
2.11.z releases.

The desire to "pip install" pulp is common. In theory, you can pip install
pulp now right from the git repositories if you just check out the desired
release tags. The challenge of course is that today the RPMs provide much
more than just the code; apache configs, /etc/pulp, /var/lib/pulp, selinux
stuff, startup scripts, etc. It would be great to move a lot of that work
to a config management system and treat that as an installer, which is
probably the biggest chunk of work currently necessary to make "pip
install" a viable deployment technique. This would be wonderful to have.
Another great benefit to this general effort is that it would open up the
possibility of installing Pulp on Debian-based systems.

Getting the code onto pypi would also be helpful, although there are
namespace challenges there. It probably just needs some thought and effort.

Help is invited for all of this. In particular, it would be great to see a
shared effort around investing in Ansible-based deployment. I'll see if we
can re-engage that effort and make sure it's easy to participate.
