Add a log statement showing the count returned by each autoscaler check.

[nathanmonteleone]

When troubleshooting more complex autoscaler policies, it can be useful to know what target count/reason each check is returning. That information was not available in the log previously. This changeset adds it as a Debug-level log.

• If a change needs to be reverted, we will roll out an update to the code within 7 days.

Thanks for the PR @nathanmonteleone!

I know it's a bit of a pain but can you please sign the CLA? Because you git history is dirty with a merge from main you've got commits from dependabot in here and that might confuse the CLA bot. You might want to rebase to clean that up as well.

Style nitpick: we don't need to guard this in the else because all code paths in the if err != nil return.
