Description

Consider the following case:
1) a subscriber connects to master;
2) a new scheduler registered as a new framework;
3) a task is launched from this framework.

In this sequence, subscriber does not have a way to know the FrameworkInfo belonging to the FrameworkId.

We should support an event (e.g. when framework info in master is added/changed).
