Is your feature request related to a problem? Please describe.
Currently external-secrets does not support integration with cloud.ru Secret Manager

Describe the solution you'd like
Cloud.ru released Secrets Manager service that offers clients the ability to safely store secrets that can later be used in other cloud services, such as kubernetes.

Describe alternatives you've considered
Vault is used as an alternative, but I would like to have native integration with cloud.ru Secret Manager

Additional context
Full documentation about the Secret Manager product is available at https://cloud.ru/docs/scsm/ug/index.html,
unfortunately, at the moment, is only available in Russian.

For integration with cloud.ru, the SDK https://github.com/cloudru-tech/secret-manager-sdk is used, at the moment it is just a gRPC client for the secret manager API, is not a full-featured SDK.
