move  from daemon_restart.go to framework/util.go

**What this PR does / why we need it**:
Moves the func `nodeExec` from daemon_restart.go to framework/util.go. This is the correct file for this func and is a more intuitive pkg for other callers to use. This is a small step of the larger effort of restructuring e2e tests to be more logically structured and easier for newcomers to understand.

[Federation] Unify the delivery methods in the ReplicaSet controller.

Unifies the federated and non-federated object delivery methods. The reconcile method that's called already checks for existence, and no other controller has a similar paradigm, so it seems reasonable to simplify it here.

Use real proxier inside hollow-proxy but with mocked syscalls

Fixes https://github.com/kubernetes/kubernetes/issues/43701

This should make hollow-proxy better mimic the real kube-proxy in performance.
Maybe next we should have a more realistic implementation even for fake iptables (adding/updating/deleting rules/chains in an table, just not on the real one)? Though I'm not sure how important it is.

rkt: Improve the Garbage Collection

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

This PR improve the garbage collection of files written inside the `/var/lib/kubelet/pods/<pod: id>`

It removes the` finished-<pod: id>` file touched during the `ExecStopPost` of the systemd unit.
It also removes the `/dev/termination-log` file mounted into containers .

The termination-log is used to produce a message from the container and collected by the kubelet when the Pod stops.
Especially for the termination-log, removing theses files will free the associated space used on the filesystem.

Fix AssertCalls usage for kubelet fake runtimes unit tests

Despite its name, AssertCalls() does not assert anything. It returns an error that should be checked. This was causing false negatives for a handful of unit tests, which are also fixed here.

Tests for the image manager needed to be rearranged in order to accommodate a potentially different sequence of calls each tick because the image puller changes behavior based on prior errors.

orphan when kubectl delete --cascade=false

The default for new objects is to propagate deletes (use GC) when no deleteoptions are passed.  In addition, the vast majority of kube objects use this default.  Only a few controllers resources (sts, rc, deploy, jobs, rs) orphan by default.  This means that when you do `kubectl delete sa/foo --cascade=false` you do *not* orphan.  That doesn't fulfill the intent of the command.  This explicitly orphans when `--cascade=false` so we don't use GC.

@jwforres I liked this easter egg :)

@kubernetes/sig-cli-bugs we should backport this to 1.6

HTML escape apiserver errors to avoid triggering vulnerability scanners.

Simple XSS scans might fetch /<script>alert('vulnerable')</script>, and
fail when the response body includes the script tag verbatim, despite
the headers directing the browser to interpret the response as text.

This isn't a real vulnerability, but it's easier to fix this here than
it is to fix the scanners.
