Feature Request

How should the problem be solved?

PR #4571 removes the grafana.image.version field, thus restricting using our own image tag. This is caused because of the tight coupling between the linkerd version. This prevents grafana image tag from being upgraded, when grafana.image.version is present in linkerd-config-addons

What problem are you trying to solve?

Ideally there should not be a tight dependency between add-on upgrades and control plane upgrades.

What do you want to happen? Add any considered drawbacks.

Support image overwriting without running into the upgrade problem

Any alternatives you've considered?

Is there another way to solve this problem that isn't as good a solution?
