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.
