build: include MirrorDaemonCount in the ConfigMap API

It seems that original commit 4c2d2ca modified the API under the
vendor/ directory. Weirdly this did not cause any issues?! The change
should have been done in the api/deploy/kubernetes/ file instead, that
gets sync'd after running "go mod vendor".
