in the XenServer pool for GRE tunnel networks
Fix uses XenServer recommended way
Network.other_config:assume_network_is_shared=true
which ensures bridge is created automatically on hosts in the pool for
GRE tunnel networks. Fix also gets rid of error prone custom logic that ensures
bridge is created by plugging a VIF into the dom0 and connected to
GRE tunnel network.
