Description

A HA backup broker in a cluster rejects client connections. This was previously done in a ConnectionObserver registered during Plugin::initialize. However that left a window before the observer was registered when clients could connect. This showed up as a sporadic failure of the failover test. This patch moves the creation of the observer to Plugin::earlyInitialize, which is guaranteed to be called before the broker starts listening for clients.
