ADAP-835: Optimize manual refresh on auto-refreshed materialized views

[mikealfare]

resolves dbt-labs/dbt-core#6911

Problem

dbt run will issue a manual refresh of a materialized view if there are no changes detected during a run. This happens regardless of whether the materialized view is setup to be automatically refreshed. If the materialized view is already scheduled to be refreshed, there is no need to insert an additional refresh. This will add cost and potentially introduce unexpected data as the refresh schedule will not match what's set with the extra refresh.

Solution

dbt will inspect the materialized view to determine if it is set to automatically refresh. If it is, and there are no changes, then dbt run will do nothing. If it is not set to automatically refresh, then dbt run will issue a refresh command.
