[Add tasks related to bucketing function]
T375900: Allow users to override experiment enrollment
QA MPIC backend
Maintainer Docs [needs task]
User Docs [needs task]

Please note: this goal has changed form "Successfully support Growth team’s A/B test data collection". The Growth team has decided there was not yet a cost benefit for using our nascent bucketing function and will not use it for their experiment. They are however using the client libraries and will be writing up a full feedback document that we can review and use to inform our next phase of work.
