Title: Do not console.warn non-sense Error

`console.warn` in lib/PoolCluster.js is useless, for it does not tell me which node is suffering error and the details of the node.
Instead, we should emit a "warn" event with pool, which is much more useful. Anyone who concerns about these messages can handle it themselves.
