Reland "Reland "HaTS: Add HaTS Api Key""

This is a reland of commit 8475f68315
It turns out google_apis/internal is not rolled automatically, so although I had submitted https://chrome-internal-review.googlesource.com/c/chrome/google_apis/internal/+/6151544, it has to be rolled manually. This roll has been done in https://crrev.com/c/4859186.
