Alerting for prometheus have been depending on the step parameter from each query.
In https://github.com/grafana/grafana/pull/9226 we changed the behavior for step in the
frontend which caused problems for alerting. This commit fixes that by introducing a default
min interval value so alerting always have something to depend on.
closes#9777
Set MaxIdleConn and MaxOpenConn when using the GF_DATABASE_URL configuration. Also added GF_DATABASE_DEBUG flag to print SQL statements and SQL execution times.
See #9784 for the details.
