Chart upgrading was failing due to some immutable fields are needed to be upgraded before the jobs can be upgraded. For solving this issue, helm.sh/hook annotations with post-install and post-upgrade has been added. As for hook-weight annotations, we have added these to control the flow of the jobs with hook creation as the jobs are dependent. Like, db-init jobs need to run before db-sync and so on. Also, helm3_hook value is added in values.yaml file in case hooks needs to be disabled if needed.
