Defines a vsock device, backed by a set of Unix Domain Sockets, on the host side. For host-initiated connections, Firecracker will be listening on the Unix socket identified by the path uds_path. Firecracker will create this socket, bind and listen on it. Host-initiated connections will be performed by connection to this socket and issuing a connection forwarding request to the desired guest-side vsock port (i.e. CONNECT 52\n, to connect to port 52). For guest-initiated connections, Firecracker will expect host software to be bound and listening on Unix sockets at uds_path_<PORT>. E.g. "/path/to/host_vsock.sock_52" for port number 52.
