Refactor volume controller parameters into a structure
`persistentvolumecontroller.NewPersistentVolumeController` has 11 arguments now,
put them into a structure.
Also, rename `NewPersistentVolumeController` to `NewController`, `persistentvolume`
is already name of the package.
Fixes#30219
We had another bug where we confused the hostname with the NodeName.
To avoid this happening again, and to make the code more
self-documenting, we use types.NodeName (a typedef alias for string)
whenever we are referring to the Node.Name.
A tedious but mechanical commit therefore, to change all uses of the
node name to use types.NodeName
Also clean up some of the (many) places where the NodeName is referred
to as a hostname (not true on AWS), or an instanceID (not true on GCE),
etc.

Use secrets for glusterfs provisioning passwords
- no plain password in StorageClass!
- fix the style along the way
- use PV annotations to pass the configuration from provisioners to deleters, inspired by Ceph RBD provisioning.
~~Proposing 1.4:~~
~~- GlusterFS provisioning is a new 1.4 feature~~
~~- if we release GlusterFS provisioner as it is now, we need to support it's API (i.e. plaintext passwords) until 2.0~~
~~- it can break only GlusterFS provisioning, nothing else~~
~~- it's easy to revert~~

Tune down initialDelaySeconds for readinessProbe.
Fixed#33053.
Tuned down the `initialDelaySeconds`(original 30s) for readiness probe to 3 seconds and `periodSeconds`(default 10s) to 5 seconds to shorten the initial time before a dns server pod being exposed. This configuration passed DNS e2e tests and did not even hit any readiness failure(for kube-dns) with a GCE cluster with 4 nodes during the experiments.
For scaling out kube-dns servers, it took less than 10s for servers being exposed after they appeared as running, which is much faster than 30+s(the original cost).
`failureThreshold` is left as default(3) and it would not lead to restart because the status of readiness probe would only affect whether endpoints being exposed in service or not(in the dns service point of view). According to the implementation of [prober](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/prober/worker.go), the number of retries for readiness probe is unbounded. Hence there is no obvious effect if the readiness probe fail several times in the beginning.
The state machine of prober could be illustrated with below figure:
I want to see the e2e result of this PR for further evaluation.

Unwrap aggregates of size 1 when writing errors
Our special error logic was being defeated by aggregates.
Also, only use aggregate in get when we actually are dealing with
multiple errors.
@kubernetes/kubectl
For other kubectl reviewers - no one should use an aggregate unless you are ranging over a list, and even then ask yourself whether you really care about returning all errors.

Copy auth plugin to client-go repo
client-go doesn't copy the [auth plugin](https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/client/auth/plugins.go). This causes user cannot access cluster run by GKE. User will see error "No Auth Provider found for name gcp".
This PR fixes this issue. It's marked as WIP because I'll need to rebase after #32906 gets merged. Also, the fix needs to be cherry-picked into 1.4 branch to update client-go/1.4.

Add a lower-bound for conntrack (128k default)
Fixes#32435
kube-proxy will use a lower-bound, default 128k, for conntrack records. This
is in concert with the per-core scaling factor.

vSphere cloud provider: ExternalID/InstanceID not returning appropriate error for non-existing VM
Addresses #33215.
When vCenter returns error vm not found, this is now being translated to
the appropriate error 'cloudprovider.InstanceNotFound' which indicates
to Kubernetes node controller that the VM is in fact not found.

controller: don't retry deployments with overlapping selectors
Returning an error will cause the deployment to be requeued. We should
just emit an event for deployments with overlapping selectors and silently
drop then out of the queue. This should be transitioned to a Condition
once we have them.
