Check for OperatorDeployInfo not null is optional as it will be necessary
to dereference OperatorDeployInfo.id and OperatorDeployInfo.name in the
OperatorContext constructor, so NullPointerException will be raised anyway.
Annotating OperatorDeployInfo parameter as `@NotNull` is good, but we don't
follow this practice in other places.
