/**
 * Implements a Converter that converts RoutedRpcRegistration instances. This is to work around an issue
 * when injecting a RoutedRpcRegistration instance into a bean where Aries is not able to convert the instance
 * returned from the RpcRegistryProvider to the desired generic RoutedRpcRegistration type specified in the
 * bean's setter method. This is because the actual instance class specifies a generic type variable T and,
 * even though it extends RpcService and should match, Aries doesn't handle it correctly.
