BZ#1127816 - HA neutron sets pcs properties before starting service

Make quickstack::neutron::all contain neutron::server, so that
resources after quickstack::neutron::all also are after
neutron::server.

BZ#1127816 - HA neutron sets pcs properties before starting service
do not provide a default for network_public_network

If quickstack::nova_network::compute is called with network_public_iface
set but no value provided for network_public_network, the default value
for network_public_network will be used in the call to find_nic(), which
will in almost all cases cause find_nic() to return an empty value.

This patch resolves that problem by removing the default setting for
network_public_network.
