Add Python Jira module to requirements

The Jira module is now available in global-requirements:
https://review.openstack.org/#/c/562151/

Since the Jira module is now loaded by default, it always
needs to be installed. If a future change prevents loading
of the Jira module unless the Jira plugin is enabled then
this change can be reverted.
