Support Routing to cluster with the least queue for the User, fallback to existing Cluster Queue based Routing approach if user level queue size are equal/no-queue.
Makes use of "ui/api/query?state=QUEUED" on the coordinator to fetch the current queued queries on the cluster.
This is internal change to the routing manager but given this is a sizable change, I plan to bump up the version to
1.9.0with this release
