Make it possible to update Knative
Description
Currently it is not possible to update Knative through the user interface once it is installed.
The most reasonable upgrade path is: 1. remove the cluster 2. create a cluster 3. install everything from scratch.
This is not really convenient and it is a problem when it comes for security updates.
Proposal
Make it possible to (all or one):
Update Knative with just one click
Add a button that makes it possible to update Knative componenents.
Enable auto-update
In this case GitLab will take care about Knative being up-to-date automatically.
