Stop logging full object in RPC push code

We already log the full object on the agent side
and other server methods log important parts of
the object so there isn't much to gain logging the full
OVO components passed to this function's args.

This adds a specific debug statement that just indicates
the types, IDs, and revision_numbers being pushed out so
they can still be correlated with received objects on the
agent side.
