[cuisongliu]

This pull request includes several changes to the internal/controller package, focusing on improving the handling of context values, imports, and annotations in Kubernetes resources. The most important changes include adding a new context key type, updating import statements, and modifying annotations in the syncControllerSTS method.

Context Handling Enhancements:

• Introduced a new ctxKey type to manage context values more effectively in internal/controller/automq_controller.go. ([internal/controller/automq_controller.goR54-R55](https://github.com/cuisongliu/automq-operator/pull/32/files#diff-518ef86c8cca5a146f361950294aa1dfdfd9bfad14b9c8250befa4a56f6f8b9dR54-R55))
• Added a context value for hash-configmap in the scriptConfigmap method. ([internal/controller/automq_controller.goR236](https://github.com/cuisongliu/automq-operator/pull/32/files#diff-518ef86c8cca5a146f361950294aa1dfdfd9bfad14b9c8250befa4a56f6f8b9dR236))

Import Statement Updates:

• Updated import statements in internal/controller/automq_controller.go to include time and hash, and removed redundant time import.
