Review comment:
The information which `rfIdentifier2fetched` map is storing can be
implicitly derived using first map `rfIdentifier2RFW`. Once the
`RuntimeFilterWritable` is consumed just remove it from first map. Then in
`closeReceivedRFWs` just call `close` on the `RuntimeFilterWritable` which is
present.

> The current implementation of JPPD to find the probe side wrapper depends on
> the GroupScan's digest. But there's no promise the GroupScan's digest will
> not be changed since it is attached to the RuntimeFilterDef by different
> storage plugin implementation logic.So here we assign a unique identifier to
> the RuntimeFilter operator, and find the right probe side fragment wrapper by
> the runtime filter identifier at the RuntimeFilterRouter class.
