This commit adds the kubernetes plugin kubectl cert manager to the iso.
This is used to convert old v1alpha2 and v1alpha3 cert manager
resources to v1 during a system upgrade. The plugin is not required
for debian because there are no old cert manager resources to convert.
Test Cases:
PASS: Convert our default DC certificates and issuers using
kubectl cert manager
