should still be able to query the EC2 inventory, although

Add support for neutronclient

The quantum_* modules will now try neutronclient first, and fall back
to quantumclient. If that fails, error out.

The code now references neutron instead of quantum in all internal
cases.
Specify internal_network_name

This allow one to specify a specific internal network name for the case
where there is more than one nic on an instance. Without this, the list
of ports may not return the correct order. Therefore, it is necessary
to specify the exact internal network to attach the floating ip to
django_manage need not require virtualenv in PATH

The virtualenv parameter to the django_manage command is used to locate
the virtualenv and build it if necessary.  Access to the virtualenv
executable is only needed if the virtualenv directory doesn't exist and
needs to be built.  This patch allows for the situation where a
virtualenv that is not in the PATH was used to create a virtualenv prior
to running the django_manage module.
