fixed a typo
whitelist noads query parameter and map it as a property in Application and Article controllers
disable top leaderboard ad if noads=1 passed in URL
first implementation of disabling ads: done
cleaner way of disabling ads
removed unecessary expect() calls
new method for Ads module and tests, tests, tests ;)
removed the method needed only for tests in Ads module and used a different approach
added computed property showAds and a useful warning for devs
CR changes: no whitespace inside parens
CR changes: moved noads from application controller's queryParams whitelist to article controller's one
CR changes: go with snake_case for query params in Mercury - except the legacy params
CR changes remove willInserElement hook for now - we have only 3 ad slots and we pass the noAds parameter there
reverted moving noAds only to ArticleController since we have an ad slot in application template
changed logic of AdSlotComponent::showAds() so it works like in Oasis, added unit tests for it
simplify showAds property, treat noads as noads=1
more modifications to noAds support: updated unit tests so it reflects Oasis behavior
