Remove EndpointConfig.Transport from the return value of the
registry.notifications.endpoints expvar.Func. It results in an empty
value for that expvar variable under Go 1.7 because it is a non-nil
*http.Transport, which Go 1.7 can no longer encode as JSON.

The Hub registry generates a large volume of notifications, many of
which are uninteresting based on target media type. Discarding them
within the notification endpoint consumes considerable resources that
could be saved by discarding them within the registry. To that end,
this change adds registry configuration options to restrict the
notifications sent to an endpoint based on target media type.

The EndpointConfig struct in the notifications package has some config
fields for a notification endpoint. This commit adds the ability to pass
in an *http.Transport to use when notifying that endpoint of an event.
This is especially useful for endpoints that use self-signed CAs.

Since the notifications package is now decoupled from storage, we are moving it
to the root package.
