KEDA metrics api server not honoring log level

[mrparkers]

Report

Exact same issue as #3053 and #2316. Trace logs appear in stdout despite running the pod with -v=0.

The trace logs look like this:

I1030 16:06:17.184854       1 trace.go:236] Trace[1893921442]: "List" accept:application/vnd.kubernetes.protobuf, */*,audit-id:7da6ab1a-9d01-4c75-b3fc-11fcbee2f159,client:172.16.123.93,protocol:HTTP/2.0,resource:foo-303xx1-5-3022xx1-5,scope:namespace,url:/apis/external.metrics.k8s.io/v1beta1/namespaces/bar/foo-303xx1-5-3022xx1-5,user-agent:kube-controller-manager/v1.27.6 (linux/amd64) kubernetes/b6911bf/system:serviceaccount:kube-system:horizontal-pod-autoscaler,verb:LIST (30-Oct-2023 16:06:16.651) (total time: 533ms):

Trace[1893921442]: [533.696851ms] [533.696851ms] END

Expected Behavior

Trace logs should not show up when -v=0.

Actual Behavior

Trace logs show up when -v=0.

Steps to Reproduce the Problem

1. Deploy keda metrics api server with -v=0.
2. Observe the trace logs in stdout
