Bump autoscaler resources to be equal to controller resources #10865

Merged

Proposed Changes

The autoscaler is a controller of a few resources after all and it's doing a lot more work asynchronously too. We've (Red Hat Openshift Serverless) been seeing quite a lot of CPU throttling in the autoscaler and the limits and requests seem indeed to be fairly low given the work the autoscaler is doing. This aligns the resources with the controller but we surely need a better way to set these values and/or communicate what the expected amount of handled resources can be.

Release Note

Bumped the resource request and limits of the autoscaler to 100m/100Mi, 1000m/1000Mi respectively.

checked with @cdlliuy and our prod numbers based on load testing are a fair bit higher even than this so this seems likely to be a better out of the box experience for people
