Title: Check that connection is valid before sending requests

When using slacker-cluster, if a slacker client makes a request after the server has been killed but before Zookeeper has pushed a node update, the slacker client can get stuck trying to send a request using a dead connection.

This change adds a last connection validity check before the send, which prevents the issue.
