The SizeResponse processor ignores remote exceptions by implmenting this method. Ignoring
remote exceptions is acceptable since the SizeMessage is sent to all Nodes and all
{@link SizeMessage.SizeReplyMessage}s are processed for each individual bucket size. The hope
is that any failure due to an exception will be covered by healthy Nodes.
