### Description of PR
We add an phone alarm on metrics sumOfActorCommandQueueLength when it
beyond 3000.
Recently, we received the alarm and we found that `DatanodeCommand[] cmds`
with array length equals to 0 was
still put into queue and incrActorCmdQueueLength.
When processedCommandsOpAvgTime is high, those empty cmds were put into
queue every heartbeat intervel.
sumOfActorCommandQueueLength should better only record valid commands.
