xenapi: Add qemu-utils as a cinder dependency

If you are using xenapi, your system won't have qemu-img installed. This
patch adds the package qemu-utils to the list of cinder
apts/rpms/suse-rpms, thus devstack will pull the required binaries.

Fix python exec prefix on SUSE.

"sudo python setup.py develop" installs to /usr/bin on SUSE

Otherwise it fails with "stack.sh:191 g-api did not start".

Add python-libguestfs to RPM list

libguestfs appears to be the best way to access images for injection,
so add the python bindings to the RPM list.  Indeed, on RHEL it is the
only way, because the fallback of nbd access isn't available.  There,
this change prevents a lot of errors in nova.virt.disk.vfs.localfs
when it can't import the nbd module.

Enhance DevStack to allow user to specify the
following customizations for the predefined networks
created on startup (default in parenthesis):

PRIVATE_SUBNET_NAME    - Name of the local subnet (private-subnet)
PUBLIC_SUBNET_NAME     - Name of the public subnet (public-subnet)
PUBLIC_NETWORK_GATEWAY - IP for the public subnet (172.24.4.225)

Moved NETWORK_GATEWAY into lib/quantum, along with these new
customizations.
