libffi-dev is required to install cffi and PyNaCL from tarballs.
cffi is installed from requirements.txt, so 'test' profile is not
specified.
We usual use wheel packages when installing python packages,
but tarball is sometimes used, for example, when a new version
is uploaded. I think it is worth adding it to bindep.txt
to avoid accidental gate failure.

The pep8 images in infra no longer have ssl installed by
default so we have to specify them in bindep.

Due to the high memory footprint of current Python ns-metadata-proxy,
it has to be replaced with a lighter process to avoid OOM conditions in
large environments.
This patch spawns haproxy through a process monitor using a pidfile.
This allows tracking the process and respawn it if necessary as it was
done before. Also, it implements an upgrade path which consists of
detecting any running Python instance of ns-metadata-proxy and
replacing them by haproxy. Therefore, upgrades will take place by
simply restarting neutron-l3-agent and neutron-dhcp-agent.
According to /proc/<pid>/smaps, memory footprint goes down from ~50MB
to ~1.5MB.
Also, haproxy is added to bindep in order to ensure that it's installed.

This allows to avoid installing unneeded packages when in gate, saving
some time when preparing environment for unit and other non-dsvm tests.
