Title: [TEST] For connection rules make TransportAddress the identity instead of DiscoveryNode

For unicast ping the DiscoveryNode identity is based on its id, which in that stage is a dummy value, this breaks any rule in the mock transport service.
However the TransportAddress is a valid value in unicast ping and all other places, so that is a better alternative.
