automatically override progress_bar_refresh_rate in google colab
🚀 Feature

If running on google colab, automatically assign progress_bar_refresh_rate=20 if the user didn't override the default of 1.
Motivation
Google colab is notorious for crashing because of the tqdm progress bar while training. We usually solve that by assigning a larger number to progress_bar_refresh_rate flag of Trainer. However, this is super annoying since you have to do it all the time.
Also, when writing up examples for beginners, it would be nice to just say pl.Trainer() instead of having to pass the refresh rate flag, as that may confuse newcomers.

Pitch

Put this logic in CallbackConnector, or ProgressBarBase. I'm not sure which makes more sense.
import sys


def check_if_on_google_colab():
    return 'google.colab' in sys.modules
