- Automatically close statements that are fully iterated or that have
errors, to prevent dangling statements from causing clients to hit
open statement limits.
- Empower client auto-reconnects by throwing NoSuchConnectionException
when appropriate.
- Try to close empty connections when we hit the open connection limit,
rather than failing the newly opened connection. Client
auto-reconnections mean this shouldn't cause problems in practice.
- Improve concurrency of the server by making "connections" a
concurrent map.
- Lower default connection timeout to PT5M from PT30M.

Jackson deserializes integers sometimes as int and sometimes as long,
depending on how big they are. This leads to ClassCastException
when comparing deserialized values as part of groupBy merging on the
broker.

This is useful for putting them behind load balancers or proxies, as it lets
the load balancer know which server is currently active through an http health
check.
Also makes the method naming a little more consistent between coordinator and
overlord code.
