Upgrade kubernetes dependencies to 1.9.2

[cofyc]

What this PR does / why we need it:

Upgrade kubernetes dependencies to 1.9.2. Some features requires 1.9.x API definitions. See #552, #570.

Which issue this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close that issue when PR gets merged): fixes #

Special notes for reviewer:

I splited the PR into two parts:

• Vendor files: 92504da (glide up -v followed by glide-vc --use-lock-file)
• Non-vendor changes: c7537cc

Due to some packages depending to packages under k8s.io/kubernetes which changed a lot, a lot of conflicts need to be fixed:

• Package k8s.io/kubernetes/pkg/api/v1/helper moved to k8s.io/kubernets/pkg/apis/core/v1/helper
• Remove Scheme.DeepCopy, use <obj>.DeepCopy() directly, see apimachinery: remove ObjectCopier interface(s) kubernetes/kubernetes#53525.
• Regenerate deepcopy files for snapshot CRD types (also added some hack scripts to generate it automatically)

@wongma7 As all the tests are passed, it looks good to me. PTAL.

Thanks @cofyc confirm that ceph/cephfs could be compile successfully ;-)

@cofyc and @wongma7 may we have another stable image for CephFS provisioner pushing to https://quay.io/repository/external_storage/cephfs-provisioner once getting ready?

I am now trying to integrate CephFS provisioner with Kubespray (kubernetes-sigs/kubespray#2230), which temporarily require for building local image and push to a local registry. Without the help from here, the integration procedure for Kubespray now looks absolutely insane...

I cut a release with the 1.8 deps here: https://github.com/kubernetes-incubator/external-storage/releases

I'll merge this to update deps to 1.9
