Enable bypassing online checks in kubeadm upgrade plan
Signed-off-by: Chuck Ha <ha.chuck@gmail.com>

**What this PR does / why we need it**:

This PR makes `kubeadm upgrade plan` a little nicer to use in an air gapped environment. `kubeadm upgrade plan` now accepts a version and returns that instead of checking the internet.

**Which issue(s) this PR fixes**:

Fixes kubernetes/kubeadm#698

**Special notes for your reviewer**:

I also cleaned up the tests for this section of code by adding formal names for table tests and using `t.Run`.

**Release note**:

```release-note
`kubeadm upgrade plan` now accepts a version which improves the UX nicer in air-gapped environments.

Set names for OpenStack loadbalancer members and monitors

**What this PR does / why we need it**:
This PR sets names for OpenStack loadbalancer members and monitors.
ATM names for members and monitors are empty, making it difficult to identify where they belong.

Healthmonitors will be named `monitor_<lb_name>_<index>` and members
will be named `member_<lb_name>_<index>_<node_name>`.
This naming scheme should in sync with the naming of other LB resources, e.g. pools: `pool_<lb_name>_<index>`.

Api server extra args

**What this PR does / why we need it**:

This PR will correctly override the APIServer command with the values found in APIServerExtraArgs. If none are passed in a default set of flags will be used.

This also includes cleaning up tests by using `t.Run` and naming test cases so we know what they are doing. `t.Run` also provides better testing output when coupled with a name.

At some point we stopped using the k8s version to generate this command. It is trivial to add back if we need it later, but since we don't use it now it's best for it to go. This also exposed several test that were identical. Those have been removed.

**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes kubernetes/kubeadm#760

 remove rootscopedkinds from groupmeta

builds on https://github.com/kubernetes/kubernetes/pull/63206

Since, a RESTMapping can only be determined based on a connection to a server, the only thing that needs to know the namespaced-ness of a resource is the code doing the registration.  Everything else is derived from that source of truth.  This removes the other dangling references and collapses down onto the existing namespaced-ness methods in the strategies backing the stores.

add test for sparse version encoding/decoding

This adds tests that make sure the sparse version encoding and encoding work as callers will expect, with the correct version being picked from the list.  I wrote two tests, one a theoretical test not dependent on any API and another practical test using cronjobs which are currently sparse in the registry.

@liggitt turns out that because we find exact matches, sparse versions ought to work out fine.
@smarterclayton I hate that the versioner matches on type.  I'll update that separately I think.

 kubelet: force filterContainerID to empty string when removeAll is true 

fixes https://github.com/kubernetes/kubernetes/issues/57865

alternative to https://github.com/kubernetes/kubernetes/pull/62170

There is a bug in the container deletor where if `removeAll` is `true` in `deleteContainersInPod()` the `filterContainerID` is still used to filter results in `getContainersToDeleteInPod()`.  If the filter container is not found, no containers are returned for deletion.

https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/pod_container_deletor.go#L74-L77

This is the case for the delayed deletion a pod in `CrashLoopBackoff` as the death of the infra container in response to the `DELETE` is detected by PLEG and triggers an attempt to clean up all containers but uses the infra container id as a filter with `removeAll` set to `true`.  The infra container is immediately deleted and thus can not be found when `getContainersToDeleteInPod()` tries to find it.  Thus the dead app container from the previous restart attempt still exists.

`canBeDeleted()` in the status manager will return `false` until all the pod containers are deleted, delaying the deletion of the pod on the API server.

The removal of the containers is eventually forced by the API server `REMOVE` after the grace period.

remove incorrect static restmapper from type registry

A RESTMapping can only be determined by inspecting a server since discovery is the authoritative source of mapping decisions.  This removes a deceptive method from the type registry and makes the old logic available for existing tests in a separate, clearly labeled package.

scheduler: clean up and simplify equivalence cache locking

**What this PR does / why we need it**:
This is a cleanup of the locking code for equivalence cache. There is no change to the current logic or locking. This PR has a couple of implications, though.
1. It deletes (unreachable) code that could have been used to cache predicate results that consider nominated pods.
2. Callers should no longer lock/unlock the eCache manually, so coordinating that lock with other synchronization is restricted.

Fix wrong usage of kubelet option

**What this PR does / why we need it**:

"--allow-privileged true" is incorrect usage of boolean option.
It means setting '--allow-priviledged' to its default value plus
non-existing subcommand 'true'.

"--allow-privileged false" is even more confusing as it sets
allow-priviledged flag to its default value 'true'

This is true for any boolean command line option.

Fixed this by using correct syntax --allow-priviledged=true
