Goal

As an admin, I want to modify the Tekton Hub styling to use our logo and stylesheet so that it looks and feels like our internal styling across OpenShift and internal portals.

Console allows certain modifications to the styling through the configurations provided to the admin. The goal is to follow the same pattern and allow styling modifications in Tekton Hub so customers can adjust the styling to their own brands:

• Admin can change the logo of Tekton Hub through the configurations on the cluster
• Admin can add a css stylesheet to be added to Tekton Hub through the configurations on the cluster
