ConnectionSubscription

A declared subscription: a subscriber (team/context/cogmap) wants to be told when a
connection emits events matching a selector.

The subscriber is a context, a cogmap or a team. A subscription is revoked, never deleted, so
one that matched an event stays resolvable afterwards.
