class MediatorState extends NamedLogging

Provides state management for messages received by the mediator. Non-finalized response aggregations are kept in memory, such that in case of the node shutting down, they are lost but the participants waiting for a transaction result will simply timeout. The finalized response aggregations are stored in the provided FinalizedResponseStore. It is expected that fetchPendingRequestIdsBefore operation is not called concurrently with operations to modify the pending requests.
