develop TensorBoard event-handler

Is your feature request related to a problem? Please describe.

1. Now we only have a simple example code of TensorBoard logging. All the arguments are fixed and
   can't be used in other code or user's examples.
2. The TensorBoard example is not correct because:
   (1) It doesn't show loss of every iteration, just show the loss of the last iteration in every epoch.
   (2) It doesn't show any evaluation information, should show 3D output of evaluation instead of train.

Describe the solution you'd like
Develop a general ignite Event-handler for TensorBoard, will be easier to use and extend in the future.
