[virsh net] public: rm addr cfg for pure baremetal

To prevent adding a gratuitous requirement on public being a real
Linux bridge on the jumpserver when baremetal nodes are present,
stop configuring any IP address information for the public virsh
network, allowing us to keep mocking it like we did before L3
information was read from IDF.
