When ctrl.kubeClient.Core().PersistentVolumes().Create(volume) returns no err, and storeVolumeUpdate() fails, we save PV sucessfully ,but here err is not nil,we should not run the codes next in block if err != nil {} to delete the storage asset.

add singular resource names to discovery
Adds the singular resource name to our resource for discovery. This is something we've discussed to remove our pseudo-pluralization library which is unreliable even for english and really has no hope of properly handling other languages or variations we can expect from TPRs and aggregated API servers.
This pull simply adds the information to discovery, it doesn't not re-wire any RESTMappers.

API resource discovery now includes the `singularName` used to refer to the resource.

When using a `hostPath` inside the `Pod.spec.volumes`, this PR allows to creates any missing directory on the node.

Do not reformat devices with partitions
`lsblk` reports FSTYPE of devices with partition tables as empty string `""`,
which is indistinguishable from empty devices. We must look for dependent
devices (i.e. partitions) to see that the device is really empty and report
error otherwise.
The main point of this patch is to run `lsblk` without `"-n"`, i.e. print all
dependent devices and check it output.
Sample output:

Add the ability to lock on ConfigMaps to support HA for self hosted components
**What this PR does / why we need it**:
This PR add the ability to lock on ConfigMap objects. As we self-host more and more components, ConfigMaps provides a useful resource to lock on that applies to just the component that is being added.
This allows components such as scheduler+controller manager, etc. to have a simple mechanism to allow to active-passive HA without the cost of endpoint updates.
**Related Issues**
xref: https://github.com/kubernetes/client-go/issues/28
**Special notes for your reviewer**:
We may want to deprecate endpoints locking at some point.

Add Host field to TCPSocketAction
Currently, TCPSocketAction always uses Pod's IP in connection. But when a pod uses the host network, sometimes firewall rules may prevent kubelet from connecting through the Pod's IP.
This PR introduces the 'Host' field for TCPSocketAction, and if it is set to non-empty string, the probe will be performed on the configured host rather than the Pod's IP. This gives users an opportunity to explicitly specify 'localhost' as the target for the above situations.

allow fallthrough handling from go-restful routes
This sets up the gorestful routes to fall through to a default handler and reorders the API to be ahead of the other endpoints. This makes it possible to cleanly support cases of "match, fail, try this other handler" which we'll need for API server composition.
