Figure out how we can remove/upgrade the context key strategy
We've enhanced our context key strategy to use SHA2, and made it easier setup to use a seed now. This is documented as part of the configuration but we've had to backfill the legacy strategy in gitlab, because it's somewhat difficult to migrate this.
The context key has been used downstream in reporting to link events for the same experience in an experiment together, so without migrating them somehow, we can't easily change them. At some point the likely best course of action is to only do this on current experiments, and have new experiments not do this -- but what's the best approach for doing that?
