Add ipython kernel detection and give warning when accelerator = "ddp"
Motivation
When users try to use ddp as accelerator in Jupyter Notebook or Jupyter Lab, the trainer will be stuck forever and no hints about the cause. So, to better inform developers, it will be great to detect whether the code is run in a ipython kernel.
Pitch
When users initialize a trainer by Trainer(accelerator = 'ddp') in a ipython kernel, give a warning or exception. Something like "ddp will not work in ipython kernel" should suffice.
Additional context
Please see this to implement it. I can do a PR, but I am not sure if it is appropriate to place code for detection in Trainer.__init__()
