cluster: remove salt

Nothing uses it directly. There were some dangling dependencies from GCE and Centos kube-ups, so I just copied them into respective dirs.

see #49213

```release-note
Remove deprecated and unmaintained salt support. kubernetes-salt.tar.gz will no longer be published in the release tarball.
```

Call Dial in blocking mode

**What this PR does / why we need it**:
# Tests which uncover underlying problem
On the current master code:
1. comment out stub plugin server start [here](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/cm/deviceplugin/endpoint_test.go#L127-L128)
2. run `go test  -v k8s.io/kubernetes/pkg/kubelet/cm/deviceplugin --run TestNewEndpoint --count 1`. Test succeeds.
3. run `go test  -v k8s.io/kubernetes/pkg/kubelet/cm/deviceplugin --run TestRun --count 1`. Test hangs with:
> listAndWatch ended unexpectedly for device plugin mock with error rpc error: code = Unavailable desc = grpc: the connection is unavailable

`2` does not fail even though it invokes Dial and no listening server is running. It is because currently Dial is not waiting till the connection turns to Ready state. And this case does not invokes any RPC call over the `conn` returned by `Dial`

`3` hangs because this tests involves actual usage of `conn`(client) and there it does not find listening server because we dint start and deliberately stopped in `1`.

`Dial` should be using `WithBlock` option which ensures that `conn` is returned only when connection is in `Ready` state.

After using `WithBlock` in the `Dial`, in this PR, if `1`, `2` and `3` are repeated. Both, `2` and `3`, fails at `Dial`, which is expected behavior. By `fail`, I meant Dial blocks forever if `WithTimeout` is not used or otherwise, a timeout failure.

Fix policy conflict in the CPU manager node e2e test.

**What this PR does / why we need it**:
After graduation of the CPU manager feature to Beta, the CPU manager `none` policy is ON by default. But when the CPU manager is set to use `static` policy in the node e2e test, there will always be a conflict with the policy checkpointed in the disk. This PR fixes that by deleting the state file where required. 

Manually tested in an `n1-standard-4` instance with `Ubuntu 16.04` image on GCP, which is the same machine and image type as one of the configs used in the node e2e tests. 

Use the following command to run the test locally:
`make test-e2e-node TEST_ARGS='--feature-gates=DynamicKubeletConfig=true' FOCUS="CPU Manager" SKIP="" PARALLELISM=1`

basically just:
* move all manifests into the new gce/manifests dir
* move limit-range into gce/addons/limit-range
* move abac jsonl into gce/manifests. this is gross but we will
  hopefully be able to delete this config soon. it only exists to support
  a deprecated feature.

feat(fakeclient): push event on watched channel on add/update/delete

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

This PR enables watch function for kubernetes [fakeclient](https://github.com/kubernetes/kubernetes/blob/1bcf0b0a227d57057bde1f6fd50f26224483b324/staging/src/k8s.io/client-go/kubernetes/fake/clientset_generated.go#L88). 

This fake client add watchReactorFunction by wrapping [watch.NewFake](https://github.com/kubernetes/kubernetes/blob/1bcf0b0a227d57057bde1f6fd50f26224483b324/staging/src/k8s.io/client-go/kubernetes/fake/clientset_generated.go#L98) which is a `chan Event` but actually nothing pushes objects into this channel. So all watch function called by fake client will never return or never receive any object. 

This PR intercepts ReactionFunc of `Create / Update / DeleteActionImpl` and will push the requested object to channel.

Convert ComputerName to lower case

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

When instances count is greater than 10, azure will generate instance hostname with upper cases. But kubelet always converts hostname to lower case.

So azure cloud provider should also covert OsProfile.ComputerName to lower case.

Make cluster e2e non docker specific.

Fixes https://github.com/kubernetes/kubernetes/issues/57979.

This PR:
1) Install `crictl` for GCE GCI/Ubuntu test cluster.
2) Change cluster e2e test to use `crictl`. If `crictl` is not installed, it will fall back to `docker` CLI.

Please note that, this PR:
1) Only installs `crictl` for GCI/Ubuntu image on GCE. If other image maintainers want to support this, it's very easy to install `crictl` `v1.0.0-alpha.0`:
```console
$ wget -O crictl https://storage.googleapis.com/kubernetes-release/crictl/crictl-v1.0.0-alpha.0-linux-amd64
$ chmod +x crictl
// The sha1sum is `075190a36a03beb08065f279693f3e369e70cf99`.
```
2) Only installs `crictl` for test cluster. We may want to install it by default in production cluster after `crictl` is beta in v1.10.
