[Secrets Manager] Event Handler/ Infra

[anovis]

Secrets can be configured with a list of up to 10 Pub/Sub topics. Whenever an operation is performed that modifies the secret or one of its versions, Secret Manager will automatically publish a message to each of the Pub/Sub topics on that secret. Get, List, and Access calls do not result in message publications.
