For the alpha release, the controller should be able to update humio in a way that takes all the pods down and then brings them back up on the new version.

We need a table in the readme that matches the supported operator version with the version of humio. The major and minor versions should be locked in. We should have a way in the operator to error and not run in the case where the major and minor versions of the operator and humio do not match.

For patch updates to humio, we should eventually be able to do rolling updates. But we need core to commit that patch updates to not contain schema changes.
