In the `restartKubelet` helper, we use `exec.Command`, whose
return value is the output as the command, but as `[]byte`.
The way we logged the output of the command was as value, making
the output, meant to be human readable, unnecessarily hard to read.
We fix this annoying behaviour converting the output to string before
to log it out, making pretty obvious to understand the outcome of
the command.

The server service monitors the kubelet service and restart it
once the service is down, to avoid kubelet double restarting
we will stop the kubelet service and wait until the kubelet will be
restarted and the node will be ready.

microk8s run kubelet service as `snap.microk8s.daemon-kubelet.service`, instead of `kubelet.service`.
so e2e should use `systemctl list-units *kubelet* --state=running` to find out kubelet service of microk8s.
Under e2e tests possible the situation when we restart the kubelet
number of times in the short time frame. When it happens the systemd
can fail the service restart with the `Failed with result 'start-limit-hit'.`
error.
To avoid this situation the code will reset the kubelet service start failures
on each call to the kubelet restart command.

Address review comments and move the helper function
in the `framework/kubelet` package to avoid circular deps
(see https://github.com/kubernetes/kubernetes/issues/81245)

this patch moves the helper getCurrentKubeletConfig function,
used in both e2e and e2e_node tests and previously duplicated,
in the common framework.
There are no intended changes in behaviour.

- SimpleGET: Moved to ingress sub package of e2e framework
- PollURL: Moved to ingress sub package of e2e framework
- ProxyMode: Moved to service e2e test package
- ListNamespaceEvents: Moved to e2e_node test package
- NewE2ETestNodePreparer: Removed since 59533f0cd1
Remove the "OrDie" from the name (since it doesn't "or die") and add
an extra check that there is at least 1 node available, since many
callers already did that themselves, and many others should have.
* fix duplicated imports of api/core/v1
* fix duplicated imports of client-go/kubernetes
* fix duplicated imports of rest code
* change import name to more reasonable
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods
