Summary:
Fixes T7130. Fixes T7041. Fixes T7012.
Major change here is partitioning clients. In the Phacility cluster, being able to get a huge pile of instances on a single server -- without needing to run a process per instance -- is desirable.
To accomplish this, just bucket clients by the path they connect with. This will let us set client URIs to `/instancename/` and then route connections to a small set of servers. This degrades cleanly in the common case and has no effect on installs which don't do instancing.
Also fix two unrelated issues:
- Fix the timeouts, which were incorrectly initializing in `open()` (which is called during reconnect, causing them to reset every time). Instead, initialize in the constructor. Cap timeout at 5 minutes.
- Probably fix subscriptions, which were using a property with an object definition. Since this is by-ref, all concrete instances of the object share the same property, so all users would be subscribed to everything. Probably.
Test Plan:
- Hit notification status page, saw version bump and instance/path name.
- Saw instance/path name in client and server logs.
- Stopped server, saw reconnects after 2, 4, 16, ... seconds.
- Sent test notification; received test notification.
- Didn't explicitly test the subscription thing but it should be obvious by looking at `/notification/status/` shortly after a push.

Summary: Ref T6559. Wraps WebSocket in a reasonable driver class which does event dispatch, some state management, and handles automatic reconnect.
Test Plan: In Safari, Firefox and Chrome, connected to a websocket server and sent messages back and forth. Terminated and restarted server, saw automatic reconnects successfully reestablish a connection on all browsers.
