add index on started_at column in alert groups (#2516)
# What this PR does

Adds an index on the `started_at` column in the `alerts_alertgroup`
table. For the alert groups query used by the
`check_escalation_finished_task`, this resulted in a huge performance
boost, taking the query time from 89mins to 4secs (on our largest
production dataset).
