@Krinkle has pointed out that the meta_p database has a slice column that contains the *.labsdb service names that are being deprecated. It would be nice to just have the slice label (e.g. s1) in a column, but we don't want a breaking change for tools like GUC that are expecting a valid hostname from the current field.
- Change *.labsdb to *.analytics.db.svc.eqiad.wmflabs in the current slice column.
- Add a new slice_name column that just has the sN value.
- Document the schema change and announce on labs-l
