[FLINK-3972] subclasses of ResourceID may not to be serializable
WorkerTypes are currently subclasses of ResourceID. ResourceID implements
Serializable but not necessarily its subclasses. This may lead to problems when
these subclasses are used as ResourceIDs, i.e. serialization may fail with
NotSerializableExceptions. Currently, subclasses are never send over the wire
but they might be in the future.
Instead of relying on subclasses of ResourceID for the WorkerTypes, we can
let them implement an interface to retrieve the ResourceID of a WorkerType.
