Description

Now that we are exploring a new way to manage the experiment configuration (T390036: xLab: Simplify groups and feature values), the existing JS API we have to overrides the enrollment for experiments needs to be updated to work with groups instead of variants/features.

We are also working on a new module, mw.xLab, where all the existing JS API should reside so we are going to take the opportunity to move there this functionality.

Acceptance criteria

• Overriding enrollment feature has been moved to the new mw.xLab module
• Overriding enrollment feature works with groups instead of variants/features
  • Update clearExperimentOverride to work with groups
  • Update overrideExperimentEnrollment( EXPERIMENT_NAME, FEATURE_VARIANT_NAME, FEATURE_VARIANT_VALUE) to overrideExperimentGroup( EXPERIMENT_NAME, EXPERIMENT_GROUP )
  • Add clearExperimentOverride( EXPERIMENT_NAME )
  • Keep clearExperimentOverrides() as it's
