previous evaluators checking back in for driver HA

handle the process of evaluators checking back in when driver restart, mark things as we go, currently on to local FS. better things can be done when we have the 2.4.1 fix with which we can have list of previous containers properly.
we can cetainly do that, but can we do that in seperate checkin later? this will require a new event, new java handler, and a new .NET handler (and all the bridge work that comes with it).
