Now that we have bouncerscript up and running in production mode, it's time we can address some of the improvements that have been longing around to be solved. * 100% code coverage * roll out a major release version * improve schema validation checks * remove check_uptake from kind.yml as its unused * better fail when bouncer is unresponsive * use HEAD instead of GET for product_exists * etc

Leftovers: * get review from :jlorenzo for the PR * merge in production * tweak puppet production instance to use 1.0.0 * unpin bouncerdev worker from my environment * test with a fresh new staging release that bouncer submission works

Comment on attachment 8958213 [details] Improve bouncerscript to look more presentable https://github.com/mozilla-releng/bouncerscript/commit/98487b16e3cca9ff80a1d8daeaa449e6fb737e7f

Merged to master branch but will not roll-out to production until we're fully testing this via multiple products in staging releases. Will follow-up with other PRs to: * add pre-checks for the aliases we're updating bug 1445684 * factorize common stuff among *scripts bug 1445593 After enough testing, we'll roll-out to production the whatever version we'll have then.
