Merge pull request #35832 from MrHohn/addon-manager-logs

Automatic merge from submit-queue

Expose addon manager's log by logging to file

Fixes #35823.

Use the same way as  how [`kube-proxy`](https://github.com/kubernetes/kubernetes/blob/master/cluster/saltbase/salt/kube-proxy/kube-proxy.manifest) deals with logging. We would be able to check Addon Manager's logs for Jenkins tests after this.

Would like to see the Jenkins test result to examine.
