83e7caa02c
The oslo_context.context.RequestContext was updated in oslo_context 2.2.0 to have a roles attribute. This caused the barbican request context to have an empty roles attribute. The 'inspect' library is used to make sure backwards compatibility since the current requirements for oslo_context is >= 0.2.0. Change-Id: Iafc67a6f42e46da998eaf2f5199c47f6beaf345e
