nbd: enable use of TLS with qemu-nbd server
This modifies the qemu-nbd program so that it is possible to request the use of TLS with the server. It simply adds a new command line option --tls-creds which is used to provide the ID of a QCryptoTLSCreds object previously created via the --object command line option. For example qemu-nbd --object tls-creds-x509,id=tls0,endpoint=server,\ dir=/home/berrange/security/qemutls \ --tls-creds tls0 \ --exportname default TLS requires the new style NBD protocol, so if no export name is set (via --export-name), then we use the default NBD protocol export name "" TLS is only supported when using an IPv4/IPv6 socket listener. It is not possible to use with UNIX sockets, which includes when connecting the NBD server to a host device. Signed-off-by: Daniel P.
