UI: display and export of all users permissions in an organization (PROJQUAY-4707)

[dmesser]

This provides the ability introspect the per-repository permissions of all users in an organization. This covers users that are members of teams in the organization, robots as well as individual users invite the organization (collaborators) by repository admins. This reports also includes users who, as part of their team roles, have admin or creator access at the organization level.

The reports are visualized in the team management section of the old UI (new UI does not have team management section yet) and can be exported as HTML or PDF for point-in-time compliance reports. The superuser can also create these reports from the superuser panel via PDF export without having to be member of the organization.
