Switch ns-metadata-proxy to haproxy
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.
