Matthew Jacobson 4b439b7f52 Alerting: In migration, fallback to '1s' for malformed min interval (#78614)
* Alerting: In migration, fallback to '1s' for malformed min interval

During legacy migration, when we encounter an alert datasource query 
with a min interval (interval field in the query model) that is not 
parseable, instead of failing the migration we fallback to a min interval 
of 1s and continue.

The reason for this is a bug in legacy alerting (existing for a few major 
versions) which allows arbitrary dashboard variables to be used as the 
min interval, even though those variables do not work and will cause 
the legacy alert to fail with `interval calculation failed: time: invalid 
duration`.
