Is this a BUG REPORT or FEATURE REQUEST?

FEATURE REQUEST

Now we use DirectoryOrCreate as a default HostPathType in the kubeadm configuration file, when we create user's extra volumes(like apiServerExtraVolumes). So, user can't use other HostPathType. In order to let users use other types of HostPath(like File), I think we should support HostPathType of ExtraVolumes in the kubeadm configuration file.

And if you guys think this feature is necessary, I'd like to file a PR to add this feature.
