Daniel Nephin e4a78c977d stream: document that Payload must be immutable
If they are sent to EventPublisher.Publish.

Also document that PayloadEvents is expected to come from a subscription and that it is
not immutable.

Also fix a bug in that function when only one of key or namespace were the empty string.

Daniel Nephin 61ce0964a4 stream: remove Event.Key
Makes Payload a type with FilterByKey so that Payloads can implement
filtering by key. With this approach we don't need to expose a Namespace
field on Event, and we don't need to invest micro formats or require a
bunch of code to be aware of exactly how the key field is encoded.

Daniel Nephin 6e592ec485 state: rename and export EventPayload
The subscribe endpoint needs to be able to inspect the payload to filter
events, and convert them into the protobuf types.

Use the protobuf CatalogOp type for the operation field, for now. In the
future if we end up with multiple interfaces we should be able to remove
the protobuf dependency by changing this to an int32 and adding a test
for the mapping between the values.

Make the value of the payload a concrete type instead of interface{}. We
can create other payloads for other event types.

Daniel Nephin 5f52220f53 state: fix a bug in building service health events
The nodeCheck slice was being used as the first arg in append, which in some cases will modify the array backing the slice. This would lead to service checks for other services in the wrong event.

Also refactor some things to reduce the arguments to functions.
