NEW ISSUE: Define how Policy works for SCA Eventing

In the current SCA Assembly 1.2 draft, intents and policySets are allowed on Consumers, Producers as well as on Channels.  This functionality corresponds to the manner in which
Policy is enabled on services and references.  But events are different and the connection
between producers and consumers is looser than the connection between services and references
and the concept of matching policies across the wire may not make sense for events.

The motivation behind this issue is to start discussion on how Policy would work for
events and whether it should work differently than for services and references.

All the best, Ashok
