monitoring: alert owners
Created by: bobheadxi
Adds a new required Observable.Owner
field, with predefined owners based on 2021 engineering org, as proposed in https://github.com/sourcegraph/sourcegraph/issues/12010 for RFC-189
Many of these teams don't exist yet, but it seems the ones that don't are clearly covered by an existing team in the team page (for example, backend infrastructure => current Cloud team)
Owners were assigned based on guesses, please let me know if any should change!
