Required. The relative resource name of the network to peer with
a standard VMware Engine network. The provided network can be a
consumer VPC network or another standard VMware Engine network. If the
`peer_network_type` is VMWARE_ENGINE_NETWORK, specify the name in the form:
`projects/{project}/locations/global/vmwareEngineNetworks/{vmware_engine_network_id}`.
Otherwise specify the name in the form:
`projects/{project}/global/networks/{network_id}`, where
`{project}` can either be a project number or a project ID.
