What is the current behavior?

Scenario:

• I am a ydb user
• created Storage object with config
• created Database object without config

Then I need to include some kind of thing in ydb configuration:

• I'm editing the configuration in Storage object
• After I'll restart all Storage and all Databases

Result:
I get new configuration for Storage
But on in the Database it did not turn

Issue Number: YDBOPS-9635

What is the new behavior?

• Check field .spec.configuration in Database object:
  • if config is not defined (spec.configuration == "") and encryption is not enabled (.spec.encryption == nil) then reuse Storage ConfigMap for StatefulSet. That will help to simple and clearly update configuration for YDB cluster.
  • else create/update separate ConfigMap with Database specific configuration
