What does this PR do?

Automatically override progress_bar_refresh_rate when on Google Colab.
For this, I added a IS_COLAB constant under utilities.

The changes in import were by isort.

Fixes #3786

this is just for default values adjustment? or shall we cast anything smaller than 20 in COlab to 20?

I think if the user sets it manually to a value less than 20, we should not change that. I personally haven't experienced crashes with the default 1 (although the CPU usage is significantly higher for 1 than 20).

Is there a way to find out if the user set it manually?

what if the user sets it to 1? I don't think it should change it at all. IMO a better way to handle this is generating a simple warning on trainer init, if it's less than some threshold and is on colab.

That seems better.

I actually disagree. I think its super useful as an override, less as warning. Do we have a way to tell if the user overrides?

I don't think a force override is a good idea since it doesn't crash always with low refresh rate and what if the user wants refresh_rate < 20??
