Description

Had an issue where a user was trying to access the monitor, but claimed that it wasn't listening.

After a brief debugging session, we found out that he had multiple monitors running and he was trying to access one of the "standby" instances instead of the active one.

It would be very nice to have the webserver up all the time, but when the local monitor is not the active instance, redirect the client to the current active monitor. All of the necessary information should already be present in ZooKeeper – it would just be a Jetty redirect exercise.
