[Quay] Quay UI rewrite in PatternFly - Phase 1 MVP

Goal

• The Quay UI needs to be converted to PatternFly and needs some UI paradigms modernized, like bulk selection, search, and better conveyed object/screen hierarchy. This "Phase 1" effort is to convert a sufficient amount of screens so that the new UI is useful to superusers who want to manage their on-prem quay instances. This MVP UI will be a standalone UI for the on-prem case only.

Background

• The existing Quay UI is the original CoreOS code and has become dated over the last ~10 years. The Quay UI is due for a refresh in organization and also converting to PF to be more consistent with other Red Hat products.
• Exploration should begin as to what the Quay UI would look like in PF and how it should be organized.
• We may also want to consider whether/how this refreshed Quay UI could relate to the OpenShift Hybrid Console initiative, which in some ways could be considered the UI for "OpenShift Platform Plus" (of which Quay is a part).
• katejohnson has run a research study which will help influence the new Quay IA, a diary study with existing Quay enterprise users, summarized here: https://docs.google.com/presentation/d/14-XwwLYts1z6ELQe2zDJ71yBxdbqq7bX844bbiMFt7s/edit

Outcome - definition of done

Provide updated quay UI designs to the engineering team for implementation
 
This marvel is intended to help map designs stories in this epic to specific screens, it does not reflect the latest design for each individual screen, however: https://marvelapp.com/prototype/17cd548j/screen/87063840
