/**
 * Invokes a method in all members and expects responses from members contained in dests (or all members if dests is null).

 * @param method_call The method (plus args) to be invoked
 * @param options A collection of call options, e.g. sync versus async, timeout etc
 * @return CompletableFuture A future from which the results can be fetched, or null if the RPC is asynchronous
 * @throws Exception If the sending of the message threw an exception. Note that <em>no</em> exception will be
 *                   thrown if any of the target members threw an exception; such an exception will be in the Rsp
