Upgrade status improvements given Helm as the underlying installer

[bentito]

In the clusterextension_controller.go we ask the underlying Helm client to upgrade a bundle. This may fail. Unfortunately, there are no error types for Helm upgrade errors.

Error messages could be parsed and branched on, they range from: useful for users of the API to ambiguous. Here is a sampling with links to the issues they are drawn from:

This issue is to track the need to report properly when actionable upgrade errors are found.
