Patch API changes

During upgrades of a k2s cluster the version of resources might change. Since the resources are stored in the chart version on the namespace. The versions might become invalid after such an upgrade, since the k2 API might not resolve the resoucde with the old version any more.

This option allows to migrat api version of a certain installend chart version to allow seamless upgrade to the new API.

helm patch api <chart-name> --from v1 --to v2 --kind ConfigMap --revision 1 --dry-run

This command allows to remove a resource from a chart.
