Expiration question

We seem to have this coming up repeatedly.
What naming would be more clear?
"recording_stops_in_version"?

Currently we use:
- Histograms.json uses "expires_in_version"
- Scalars.yaml uses "expires"
- Events.yaml uses "expiry_version"

We should end up using common field names and make them less confusing.
