* The pub/sub-based client presence manager uses the Redis 7 sharded pub/sub system to notify connected clients that
* new messages are available for retrieval and report to senders whether a client was present to receive a message when
* sent. This system makes a best effort to ensure that a given client has only a single open connection across the
* fleet of servers, but cannot guarantee at-most-one behavior.
* The WebSocket connection event manager distributes events related to client presence and message availability to
* registered listeners. In the current Signal server implementation, clients generally interact with the service by
* opening a dual-purpose WebSocket. The WebSocket serves as both a delivery mechanism for messages and as a channel
* for the client to issue API requests to the server. Clients are considered "present" if they have an open WebSocket
* connection and are therefore likely to receive messages as soon as they're delivered to the server. WebSocket
* connection managers make a best effort to ensure that clients have at most one active message delivery channel at
* a time.
