Review comment:
I tend to disagree, for the following reasons.
- The default `WorkerResourceSpec` is needed for both static and dynamic
slot allocation. For dynamic allocation, we need it for scenarios where some
jobs do not provide fine grained resource requirement.
- We need the default `WorkerResourceSpec` only for active RMs, but not for
standalone RM. SM does not know which RM it runs on.
- We need the default CPU cores for creating the default
`WorkerResourceSpec`, which is depending on different configuration options per
active RM. SM does not have that information.
- According to the dependency injection principle, we should try to avoid
creating dependencies inside the component if possible.
