tests: exercise NBD server in TLS mode
Add tests that validate it is possible to connect to an NBD server running TLS mode. Also test mis-matched TLS vs non-TLS connections correctly fail. Signed-off-by: Daniel P. Berrangé <berrange@redhat.com> Message-Id: <20181116155325.22428-7-berrange@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Tested-by: Eric Blake <eblake@redhat.com> [eblake: rebase to iotests shell cleanups, use ss instead of socat for port probing, sanitize port number in expected output] Signed-off-by: Eric Blake <eblake@redhat.com>
