Do not try to create temporary URLs with zero lifetime

A new option is introduced for that, which defaults to the deploy timeout
if it is set and to 1800 seconds if it is not.

+    No longer tries to create a temporary URL with zero lifetime if the
+    ``deploy_callback_timeout`` option is set to zero. The default of 1800
+    seconds is used in that case. Use the new
+    ``configdrive_swift_temp_url_duration`` option to override.
