Standby Cluster functionality

[omkaark]

What is missing?
Standby Cluster functionality. A cluster that restores data from prod backups everyday and creates backups everyday to it's own storage entity on cloud. The new functionality would basically allow users to configure daily restores through helm.

Zalando's postgres operator has a good example of this in a diagram (checkout Standby cluster bottom left) -

Why do we need it?
This helps address the issue of data drift between prod and staging environments.

Anything else we need to know?:
This would be a critical feature for us! Thank you for all the OS work!
