Carl Bergquist 5d6ed6c45f prom: add support for default step param (#9866) 
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.

Jonathan A. Sternberg bdfbc2453f Use parenthesis to surround the selected tags for influxdb queries (#9131) 
The generated queries when selecting multiple tags are incorrect. In
InfluxQL, `AND` has a higher precedence than `OR` so the condition:

    WHERE "hostname" = 'server1' OR "hostname" = 'server2' AND time > now() - 5m

This is parsed as if it were:

    WHERE "hostname" = 'server1' OR ("hostname" = 'server2' AND time > now() - 5m)

But the intention is to write a query like this:

    WHERE ("hostname" = 'server1' OR "hostname" = 'server2') AND time > now() - 5m

This change modifies the generated query so it surrounds a query with
multiple conditions in parenthesis so it doesn't conflict with the time
expression in an unexpected way.

This is currently not an issue because InfluxDB doesn't actually
evaluate the condition for the time expression correctly. It just looks
through the AST for anything that looks like a time expression and then
assumes the proper format of `AND` was used rather than validating that
it was used correctly.

Yaron de Leeuw d4f7a2bc99 minor code style: use strings.Replace fourth argument in influxdb (#8225) 
Remove 5 lines from the codebase and an unecessary function,
by calling `strings.Replace` with -1 for the fourth argument.

A better alternative to what was merged in #8037
