        sim: Add additional debug information when draining

        This patch adds some additional information when draining the system 
which
        allows the user to debug which SimObject(s) in the system is failing to 
drain.
        Only enabled for the builds with tracing enabled and is subject to the 
Drain
        debug flag being set at runtime.
