Added support for the new Jira 9+ createmeta API.

Fixes: https://github.com/DefectDojo/django-DefectDojo/issues/6963
Depends on: https://github.com/pycontribs/jira/pull/1527

If you don't have the update in the mentioned dependency than behaves as it used to - works until Jira 9 and breaks afterwards.
If you update the dependency than it will continue working after Jira 9.
With the updated dependency it will throw deprecation warnings on Jira versions [8.4 - 9).
