Tyler Goodlet 4f387ea2be Fix subscriptions and connection handling
Oh boy where to start.

- Handle broken streams in the `StreamQueue` gracefully; terminate the
  async generator.
- When a stream queue connection is unwritable discard its subscriptions
  inside the quoter task
- If all subscriptions are discarded for a broker then tear down its
  quoter task
- Use listener parent nursery for spawning quoter tasks
- Make broker subs data structures global/shared between conn
  handler tasks
- Register the `tickers2qs` entry *after* instantiating broker client(s)
  (avoids race condition when mulitple client connections are coming
  online simultaneously)
- Push smoke quotes to every client not just the first that connects
- Track quoter tasks in a cross-task set
- Handle unsubscriptions more correctly

Tyler Goodlet 4123139750 Use `Client` in watchlist app 2018-04-20 13:18:35 -04:00
Tyler Goodlet 17feb17535 Add a reliable `Client` API
In order to start working toward a HA distributed
architecture make apps use a `Client` type to talk to daemons.
The `Client` provides fault-tolerance for connection failures such
that the app will continue running until a connection to the original
service can be made or the process is killed. This will make it easier
to simply spawn up new daemon child processes when faults are detected.

Tyler Goodlet 030ecdcce8 Filter symbols and push initial quote in stream handler
Filter out bad symbols by processing an initial batch quote and
pushing to the subscribing client before spawning a quoter task.
This also avoids exposing the quoter task to anything but the
broker module and a `get_quotes()` routine.

Tyler Goodlet 6359623019 Allow broker specific subscriptions
Allow client connections to subscribe for quote streams from specific
brokers and spawn broker-client quoter tasks on-demand according
to client connection demands. Support multiple subscribers to a
single daemon process.

Tyler Goodlet f80735121c Use an async generator inside `StreamQueue`
Async generators are faster and less code. Handle segmented packets
which can happen during periods of high quote volume. Move per-broker
rate limit logic into daemon task.
