client-go: promote exec plugin support to beta
/sig auth
/kind feature
Adds a "v1beta1" API group for client authentication. Because of a lack of usage with the input parameters, these have been dropped for the beta. Would like to re-introduce them as users feel they require them.

Revert "Remove rescheduler and corresponding tests from master"
Reverts kubernetes/kubernetes#64364
After discussing with @bsalamat on how DS controllers(ref: https://github.com/kubernetes/kubernetes/pull/63223#discussion_r192277527) cannot create pods if the cluster is at capacity and they have to rely on rescheduler for making some space, we thought it is better to
- Bring rescheduler back.
- Make rescheduler priority aware.
- If cluster is full and if **only** DS controller is not able to create pods, let rescheduler be run and let it evict some pods which have less priority.
- The DS controller pods will be scheduled now.
So, I am reverting this PR now. Step 2, 3 above are going to be in rescheduler.
/cc @bsalamat @aveshagarwal @k82cn
Please let me know your thoughts on this.
```release-note
Revert #64364 to resurrect rescheduler. More info https://github.com/kubernetes/kubernetes/issues/64725 :)

kubeadm: Set the kubelet `--resolv-conf` flag conditionally on init
**What this PR does / why we need it**:
`kubeadm init` detects if systemd-resolved is running and configures the kubelet to use a working resolv.conf.
This patch also removes the warning message prompting manual user action for this configuration.

**Special notes for your reviewer**:
See the difference in `KUBELET_KUBEADM_ARGS` when running with this build and enabling the resolved daemon on Ubuntu 17.10:
```bash
root@vagrant:/vagrant/bin# bash << EOF
systemctl start systemd-resolved
./845_kubeadm init |& tail -n5
cat /var/lib/kubelet/kubeadm-flags.env
./845_kubeadm reset --force |& tail -n2
systemctl stop systemd-resolved
echo nameserver 8.8.8.8 > /etc/resolv.conf
./845_kubeadm init |& tail -n5
cat /var/lib/kubelet/kubeadm-flags.env
EOF

**Release note**:
```release-note
`kubeadm init` detects if systemd-resolved is running and configures the kubelet to use a working resolv.conf.
```
This follows the pattern `kubectl` uses for logging.
There are two remaining glog.Infof call that cannot be removed easily.
One glog call comes from kubelet validation which calls features.SetFromMap.
The other comes from test/e2e during kernel validation.
Mostly fixeskubernetes/kubeadm#852
