This reverts commit 1db33e5fff.

Reason for revert: {AttributeError} 'Namespace' object has no attribute 'experimental'

Original change's description:
> [browser-stories] gate features behind {experimental} flag
> 
> Performance infra recipes use callstats.py to run web page replays. Split (v8,
> infa, perf-infra) repositories make experimenting with callstats.py hard.
> 
> This CL creates feature gating for simplifying performance infra experiments.
