Tweak CCI config

[mthrok]

Importing the CCI tweak I found useful while working on pytorch/text#748 pytorch/text#744

• bust conda cache weekly
• rename utility directory test -> utility
• Show slowest 20 tests in log --durations 20

The cache is for conda install packages, right?

[vincentqb]

Should the name of the file be changed as well?
.circleci/test/test_sort_yaml.py → .circleci/utils/test_sort_yaml.py

[vincentqb]

Are you planning to keep the config files in sync between domains?

[vincentqb]

Oops, I meant to say: tests are failling :/

The thing is, I do not know what this script is for and I think it's obsolete. If we care as much I suggest we delete it.

I don't think that's possible. Torchtext has specific caching which does not apply to other domains.
But these changes felt "good practice to have" in torchaudio too.

Weird, rebuilding test image and will retry.

How about we don't modify it as part of this PR, and we simply delete it in the next? :) If we don't see it used anywhere, the risk is low.
