Refactor FunctionCallbackContext to FucntionCallBackResolver interface

[konczdev]

Expected Behavior

Introducing FucntionCallBackResolver would enable more flexibility and control over how to add FunctionCallbacks to a request.

public interface FunctionCallBackResolver {

	public FunctionCallback getFunctionCallback(@NonNull String beanName, @Nullable String defaultDescription);
}

public class ApplicationContextFunctionCallbackResolver implements FunctionCallBackResolver, ApplicationContextAware {

    //the current implementation of FunctionCallbackContext 

}

Current Behavior

There are 2 options now how to add FunctionCallbacks to a Request

• manually register with FunctionCallingOptions
• automatically resolved from the ApplicationContext using the FunctionCallbackContext

Context

What are you trying to accomplish?

• Custom logic for dynamic function resolution

What other alternatives have you considered?
Are you aware of any workarounds?

• Making some less elegant logic around prompt options building.
