compute/sql_exporter: Bump max WSS window from 1h -> 3h

Browse Source 
Concretely, this:

1. Changes the normal (public) exporter to add a new 3-hour working set
   size label onto the existing 5-minute, 15-minute, and 1-hour values.

2. Extends the range on the autoscaling exporter from 1..60 minutes to
   1..180 minutes -- keeping the same density, just 3x longer.
