Review comment:
Yeah, adding this here helps for this initial version. Could we add
something like `storageInfo: Option[Serializable]`, which could be used to
store extra information for different disaggregated shuffle solutions? e.g.
storageInfo could be remote storage file path(s) or remote shuffle server(s).

Review comment:
Original BlockManagerId extends `Externalizable`, I think
`Externalizable` here for `Location` is ok.
