Fix screenrc for nova-compute

When devstack creates stack-screenrc, it includes unescaped "
characters that cause failures starting nova-compute.  This fix
changes the " to ' so there isn't a conflict.

xenapi - cleanup network configuration

The Xenserver/XCP part of devstack was configuring the hypervisor's
connectivity to the outer world, by adding VLANs, and physical
interfaces to the virtual networks. It added a lot of complexity, and
made it hard to get started with XenServer. This patch removes that
extra complexity, so it is left as an exercise for the user.
