The gRPC API of the concordium node should provide an endpoint InstanceStateMembershipProof
for constructing merkle membership proofs of a given key and value in the state of a given instance of a given trusted block hash.
This endpoint returns an error if the provided block hash is prior to the protocol version 7.
