Uses kubectl apply to create or update crds

Use kubectl apply instead of the kubectl create command to create crds, so crds could be updated accordingly. BTW: It's clear that updates of crds are not recommended, the new version should be added instead. But sometimes we do need some small changes on those crds and without backward compatibility issue.
