This is a common need for features, and having these use a standardized
class name will make using them a lot easier.

Throw a runtime exception if the TOC experiment is setup correctly.
Otherwise this leads to confusion.
There must be 3 buckets, with 0 unsampled and equally weighted
control and experiment.

- Include temporary feature requirement for TOC A/B test.
- Assumes 100% of logged-in users with even/odd user ids
being assigned to treatment/control buckets respectively.
- Sampling rates passed in by config are not considered
during bucketing.
- Update hook for adding needed TOC A/B test body classes.
- Add test for temp feature.
Note: the temporary feature requirement and associated hooks
should be removed once the 2nd TOC A/B test concludes.

The LatestSkinVersionRequirement is problematic for various reasons:
1) It uses the "useskin" query string
parameter which may or may not refer to the correct
skin (in the case of a non-existent skin it will always come to the conclusion that
it is not modern Vector and thus must be legacy).
2) It uses the User object which may or may not be safeToLoad
depending on when called.
The feature seems redundant at this point, as we are separating code
into separate classes Vector and Vector22 and all the features only apply
to modern Vector. I suggest we remove it and use the features explicitly in the skin
intended.

Given Wikidata is the only project using modern Vector,
and the only project where the search API is not applicable,
this will result in a loss of autocomplete on Wikidata.org
which will fall back to the non-JS mode.

Before this commit the `languageinheader` query param would only take
effect if the A/B test was enabled AND the query param was set. Per
T282543, we want the query param to take effect regardless of the state
of the language/AB test config.
To see new treatment, set `languageinheader=1`.
To see old treatment, set `languageinheader=0`.

* 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.

We expect the vast majority of requirements and features to be defined
in services as possible. However, there are some "complex" requirements
that require additional application/HTTP request state. Unfortunately,
service wiring is done before some of that state is available.
I65702426 attempted to work around this by requiring clients of the
Feature Manager to pass that additional state on every interaction with
the system. Those complex requirements would then select the parts of
the state that they required when it was required. However
implementations of \IContextSource are God objects and their use should
be limited.
Whilst reviewing I65702426, Stephen Niedzielski mentioned that the
application state being available is a requirement. This remarkably
simple solution:
- Keeps the Requirement interface and FeatureManager API free of God
objects;
- Is true to the nature of the Feature Manager - it makes clear and
centralizes the various checks for application state being available
across the codebase; and
- Inject a Requirement implementations' dependencies at construction
time
It just so happens that the $wgFullyInitialised variable flags whether
the application state is available...
Changes:
- Add the the FeatureManager\Requirements\DynamicConfigRequirement class
and tests. The DynamicConfigRequirement lazily evaluates a single
configuration value whenever ::isMet is invoked
- Register an DynamicConfigRequirement instance, configured to evaluate
$wgFullyInitialised while constructing the Vector.FeatureManager
service

FeatureManager::registerRequirement established the interface for a
requirement: its name and whether it's met.
However, the Feature Manager also needs to handle scenarios where a
requirement needs additional context before it can be considered met.
That context may not be available when the application is booting, e.g.
checking if the user is logged in; or the logic is complicated enough
that it should be under test.
Changes:
- Add the Requirement interface and update FeatureManager to work with
implementations of it
- Maintain B/C by constructing an instance of a the SimpleRequirement
DTO

As was noted in https://phabricator.wikimedia.org/T244481#5859513, the
term "set" doesn't seem natural. Piotr Miazga (polishdeveloper, pmiazga)
and Nicholas Ray (nray) suggested a number of good replacements,
including "requirement." Serendipitously, this term is already used in
FeatureManager's documentation.

With complex additions to Vector's codebase like the Desktop Improvement
Program upcoming, it's important that we have a shared, intuitive
language to talk about features and their requirements. Centralising
the registration of features and creating an API satisfies does exactly
this.
This change introduces a greatly-reduced version of Piotr Miazga's
(polishdeveloper, pmiazga) original proposed API and associated
scaffolding classes for feature management in Vector, which itself was
based upon his work in MobileFrontend/MinervaNeue. This is done to
establish a foundation upon which we can build the more sophisticated
parts of Piotr's proposal in a piecemeal basis, thereby minimising risk.
Distinct from Piotr's proposed API is the ability to register sets and
features that are always enabled or disabled.
Additionally:
- A Vector.FeatureManager service is registered but not used
- A list of proposed immediate next steps is included
