Currently only features that are associated with LocalSettings configuration can be overriden by query string. Going forward we'd like to expand this to apply to user preference too. A generic OverrideableRequirement is created. The existing OverridableConfigRequirement is refactored to extend OverrideableRequirement The /UserPreferenceRequirement now extends it This allows http://localhost:8888/wiki/Spain?vectortypographysurvey=1 to work Bug: T347900 Change-Id: I11efd6b07192d5d2333f4506e9d87a8c0638d657
