Fix typo in local-up-cluster
Use curly braces instead of round ones for bash variable expansion. The
script complains about unknown ROOT_CA_FILE when running with
KUBE_ENABLE_CLUSTER_DNS=true.

always allow decoding of status when returned from the API
`unversioned.Status` should be able to come back from any API version and still be properly decoded. This doesn't happen today by default.
@smarterclayton Our projectrequest endpoint returns a `Status` object on a 200 return from list to indicate everything went well. This (or something like it) is needed to make the API accepted by `kubectl`. Alternatively, we change the API to return a different (still not a `Project`) value from list, which still feels wrong.

Populate Node.Status.Addresses with Hostname
This PR is supposed to address #22063
Currently `NodeName` has to be a resolvable dns address on the master to allow apiserver -> kubelet communication (exec, log, port-forward operations on a pod). In some situations this is unfortunate (see the discussions on the issue).
The PR aims to do the following:
- Populate the `Type: Hostname` in the `Node.Status.Addresses` array, the type is already defined, but was not used so far.
- Add logic to resolve a Node's Hostname when the apiserver initiates communication with the Kubelet, instead of using the Nodename string as Hostname.
```release-note
The hostname of the node (as autodetected by the kubelet, specified via --hostname-override, or determined by the cloudprovider) is now recorded as an address of type "Hostname" in the status of the Node API object. The hostname is expected to be resolveable from the apiserver.

promote /healthz and /metrics to genericapiserver
Promotes `/healthz` to genericapiserver with methods to add healthz checks before running.
Promotes `/metrics` to genericapiserver gated by config flag.
@lavalamp adds the healthz checks linked to `postStartHooks` as promised.

clean up client version negotiation to handle no legacy API
Version negotiation fails if the legacy API endpoint isn't available.
This tightens up the negotiation interface based to more clearly express what each stage is doing and what the constraints on negotiation are. This is needed to speak to generic API servers.

Don't rely on device name provided by Cinder
See issue #33128
We can't rely on the device name provided by Cinder, and thus must perform
detection based on the drive serial number (aka It's cinder ID) on the
kubelet itself.
This patch re-works the cinder volume attacher to ignore the supplied
deviceName, and instead defer to the pre-existing GetDevicePath method to
discover the device path based on it's serial number and /dev/disk/by-id
mapping.
This new behavior is controller by a config option, as falling back
to the cinder value when we can't discover a device would risk devices
not showing up, falling back to cinder's guess, and detecting the wrong
disk as attached.

Add BindNetwork to genericapiserver Config
This is needed for downstream use:
`BindNetwork` is the type of network to bind to - defaults to "tcp4", accepts "tcp", "tcp4", and "tcp6".

Corect filtering of OpenStack LBaaS resources to delete
Neutron's API ignores unknown parameters. When listing pools etc, K8
attempts to filter on "LoadBalancerID", which is not a valid filter.
As such, it is ignored by Neutron, and a list of all pools is
returned. K8 then proceeds to delete each of the pools.
Instead, we now double check the resources really belong to the LB
we're trying to delete.

[Kubelet] Use the custom mounter script for Nfs and Glusterfs only
This patch reduces the scope for the containerized mounter to NFS and GlusterFS on GCE + GCI clusters
This patch also enabled the containerized mounter on GCI nodes
Shepherding multiple PRs through the submit queue is painful. Hence I combined them into this PR. Please review each commit individually.

Retry "godep restore" once in verify-dockerized.sh
This should fix#36110. The current flake rate is 0.5%, so with the
unrealistic assumption of uncorrelated flakes, a single retry will bring
it down to <0.01% flake rate.

Please review only the last commit here. This is based on PR #35593 which will be reviewed independently.
I am intentionally not including the unit tests in this PR to better distribute and parallelize reviews. This PR is already big.
