chore(samples): Snippet Generating Script: part 2 - moving the snippe…

…ts to new format (#225) * chore(samples): Snippet Generating System Preparing the SGS (Snippet Generating System) script to handle the burden of duplicated code in the samples. * 🦉 Updates from OwlBot See https://github.com/googleapis/repo-automation-bots/blob/main/packages/owl-bot/README.md * chore(samples): Making linter ignore the test fixtures. * chore(samples): Update region tags that shouldn't be region tags. * chore(samples): Syntax fix for Python 3.6 * Removing the 3.8 walrus syntax * Fixing test requirements * chore(samples): Trying to make the tests work * Cleaning up noxfile. * 🦉 Updates from OwlBot post-processor See https://github.com/googleapis/repo-automation-bots/blob/main/packages/owl-bot/README.md * Removing bonus requirements file as it confuses the system. * One more try to fix tests. * Changing README to make snippet bot happy * chore(samples): Changing the sampels structure to use SGS * Fixing some tests. * Adding custom hostname files. * Making tests work again. * 🦉 Updates from OwlBot post-processor See https://github.com/googleapis/repo-automation-bots/blob/main/packages/owl-bot/README.md * Making lint happy. * Making tests run faster with parallelism. * 🦉 Updates from OwlBot post-processor See https://github.com/googleapis/repo-automation-bots/blob/main/packages/owl-bot/README.md * WIP. * 🦉 Updates from OwlBot post-processor See https://github.com/googleapis/repo-automation-bots/blob/main/packages/owl-bot/README.md * Apply suggestions from code review Co-authored-by: Anthonios Partheniou <partheniou@google.com> * Applying comments from review.
