At this time all iSCSI tests were using local address 127.0.0.1 for both sides of connection. This patch changes iSCSI tests to use separate veth (virtual ethernet) interfaces. It will allow to actually verify functionality when using different target and initiator IPs. Veth are used as most closely resembling real enviroment in single host and without any network hardware required. This patch serves as a base for future VPP test changes, where veth interfaces are used as well. Note: Netmask changed to /30 temporarily and verify_iscsi_connection_rpc_methods in rpc_config disabled. Kernel will route trafic between two veth interfaces through host stack. This causes target and initiator IPs to be not as expected. Those are changed back in next patch by adding namespaces.
