Fixes LP853979 Remove the FK references for network data. Remove unused db functions that used the FK's Update db functions to not joinload Update notification to optionally take network_info if compute has it Update EC2 Api to use the network cache, falling back to rpc.call Remove test_instance_get_project_vpn_joins which tests calls not used Change-Id: I1a01ccc5ebcf7efeafe014af62be893325bb0825
