This API must be called from OnDataLossAsync method. Only one RestoreAsync API can be inflight per replica at any given point of time.
Note that exceptions thrown by this API differ depending on of underlying state provider. The exceptions that are currently documented for
this API applies only to out-of-box state providers provided by Service Fabric for Reliable Services and Reliable Actors.
