Subject: [PATCH] Add Iteration related Events (#3076)

Adds ITERATION_START, ITERATION_END, and ITERATION_CHECKPOINT to Event, Engine, and Callback. Increments iteration during training based on iteration length defined in State. Iteration length is a private variable in State and should have no effect by default.
