new criterion proposal: toolbox functionality

Related to a recently proposed blocker [0], I propose a new release criterion which would cover that case. There is a push from the Dekstop team to have toolbox as a default app in the installer iso as well. Here it is: ~~~~~~~~~~~~ Toolbox aka Toolbx should be usable. Toolbox should be able to list, create and provide the desired containerized environment to the user without root privileges. Toolbox images should be generally functional. Footnote - "What does this cover?": Toolbox's general functionality as covered by this test cases https://fedoraproject.org/wiki/QA:Testcase_toolbox ~~~~~~~~~~~~~ I think this criterion could target F39 Beta Release Criteria or Basic Release Criteria [2]. Please tell me your thoughts, thanks!
