Glance unit tests fails using oslo.config 7.0 while parsing
command line options. In oslo.config 7.0 default value of for
'required' option is changed to None from False. This 'required'
option is used to specify whether positional arguments are
required or not. As glance replicator command line tool is using
some positional arguments which are not always required causing
problems for running unit tests.
Added required=False to these positional arguments to fix this
issue.
