Subject: [PATCH] [Telemetry] Fire callback when objects are available

Fire callback from telemetry subscriber when the set of
object references changes. This allows views which use
the subscriber to register one callback, while still
ensuring that they are notified when there is new
information to show. Supports fixed position view, WTD-879.
