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.

XenServer does not create a bridge automatically when VIF from domU is connected
to internal network. So there is logic to force bridge creation by
creating VIF in dom0 connected to GRE tunnel network. But there is no
logic to delete the VIF after bridge gets created. So this fix ensure
VIF is delted when atleast there is one domU VIF connected to the
network.
