/kind breaking

/kind cleanup

/kind documentation
/kind feature
/kind hotfix
/kind release

What this PR does / Why we need it:

We don't need the full debug level on Agones for performance tests, especially since it brings us close to the quota limits on log writes.

Also updated the order of variables to make it a bit more readable.

Which issue(s) this PR fixes:
N/A

Special notes for your reviewer:

I don't have a perf test cluster locally, but this should be fine -- but will keep an eye on the perf tests to make sure, and fix anything I break.

Also curious if this makes things go faster.
