Add callback contexts
Add the notion of a callback context. This enables callbacks
to have logic around the conditions they were invoked in.
There are two context on which call back can be invoked
1) Startup: during startup all the call backs will be called
2) Signal: As part of condition match on the watched properties.
Callback would behave differently based on the context.
eg: eventCallback
1) Startup: Don't take any action.
2) Signal: Create the Dbus Object for the event.
