RemoteCache should implement size() and isEmpty()
-------------------------------------------------

             Project: Infinispan
          Issue Type: Feature Request
          Components: Cache Server
            Reporter: Galder Zamarreño

             Fix For: 4.2.1.Final, 5.0.0.BETA1


It's dead easy to do this by simply checking the stats returned by the server, i.e.

   @Override
   public int size() {
      assertRemoteCacheManagerIsStarted();
      StatsOperation op = operationsFactory.newStatsOperation();
      return Integer.parseInt(((Map<String, String>) op.execute()).get(ServerStatistics.CURRENT_NR_OF_ENTRIES));
   }

   @Override
   public boolean isEmpty() {
      return size() == 0;
   }
