Issue summary

This is a network message received from other validators. The node responds with a PoV from the local availability store.

Implementation details

When receiving a request, send availabilitystore.QueryAvailableData to the availability store via the overseer, passing the candidate hash from the request. Receive the response from the channel included in QueryAvailableData, construct a PoVFetchingResponse from it and send it to the requesting peer.

The implementation depends on support for receiving requests of request/response network protocols being implemented. This is tracked in #4453.
