Nicholas Ray 49f2b25737 Create A/B test harness for Language in header feature
* Adds ab test config to enable/disable the ab test. Defaults to `false`
(ab test disabled).

* Adds a `languageinheader` query param which only takes effect when the
ab test is enabled. The query param is cast to a bool and determines
which treatment is shown. For example, set query param to
`languageinheader=1` to see the new treatment. Set query param to
`languageinheader=0` to see the old treatment. To bucket based on the
user's id or global user's id, don't set the query param.

* Moves the language in header config work that was previously in
ServiceWiring into a `LanguageInHeaderTreatmentRequirement` class so
that unit tests can be done on most of the logic that determines whether
the language in header will show.

* Adds logic to bucket user based on [global] user id.
