Logging in Ignite

[Priyansi]

It would be nice to have a how-to guide combine all the built-in loggers that Ignite provides: ClearML, Tensorboard, MLflow, etc. See more here: https://pytorch.org/ignite/contrib/handlers.html#loggers.
The code on how to use these is already provided in https://github.com/pytorch/ignite/tree/master/examples/contrib/mnist.
When creating this new how-to guide, please:

1. Create a Jupyter Notebook, see README.md.
2. Follow the code under the basic setup of how-to guides. See this guide for reference.
3. Add explanation while creating the loggers and how to use them.
4. Run the notebook, so that the output is clearly visible, before submitting the PR.

Everyone is welcome to contribute! 🚀 Please feel free to ask any further questions below.
