Module manager

The SubscriptionManager used to manage subscription based RPCs.

The manager provides four main things in terms of functionality:

1. The ability to create unique subscription IDs through the use of the IdProvider trait. Two implementations are availble out of the box, a NumericIdProvider and a RandomStringIdProvider.

2. An executor with which to drive Futures to completion.

3. A way to add new subscriptions. Subscriptions should come in the form of a Stream. These subscriptions will be transformed into notifications by the manager, which can be consumed by the client.

4. A way to cancel any currently active subscription.
