Disable uncompressed images for tripleo-cd.

We're out of space on the undercloud, and we still can't redeploy that
so this is a workaround...

Preserve 'did we init openstack' state file.

Since we don't want deploys to reset openstack to a blank slate :).

Add haproxy element

This element will be needed for HA deployments. Haproxy will
listen on other-than-default-openstack ports so that
openstack services can be bound to all IP addresses. Keystone
endpoint urls will be updated to point to haproxied non-standard
ports.

Fixes for use behind proxy

Need to use setuptools>=1.0 in order to get fixes which
allow fetches of dependencies from pypi to work correctly
when operating behind a proxy.

Replace /var/lib/mysql path in the upstart script

The Upstart script for MySQL checks /var/lib/mysql on start, but with
the move to /mnt/state, the directory does not exist, so it fails to
start. Replace the path in the install.d script for the element.

Remove --system-site-packages from clients virtualenv

Using --system-site-packages here is causing us to use old versions of
libraries even though the correct version is installed into the
virtualenv, this is due to the order of the various directories in
sys.path. This is not a problem on newer versions of
virtualenv/setuptools although I couldn't find out exactly when it was
fixed.

In this case the specific conflict was with python-six. A recent
unrelated commit caused us to stop pip upgrading the version installed
from a package. In turn breaking several of the virtualenv installed
packages.
