CloudBees Replication Parent 2603

When an inbound WebSocket agent connects to a replica of an High Availability (HA) controller and the connection must be forwarded on to another replica, eleven native threads were consumed by the first replica’s JVM. Because most of these threads were unused, this could lead to excessive memory consumption or ulimit exhaustion under heavy load conditions. Now the WebSocket reverse proxy is reimplemented with a different client which permits more efficient thread pool usage.
