Run with: constellation upgrade execute --helm.
This will only upgrade the helm charts. No config is needed.
Upgrades are implemented via helm's upgrade action, i.e. they
automatically roll back if something goes wrong. Releases could
still be managed via helm, even after an upgrade with constellation
has been done.
Currently not user facing as CRD/CR backups are still in progress.
These backups should be automatically created and saved to the
user's disk as updates may delete CRs. This happens implicitly
through CRD upgrades, which are part of microservice upgrades.
