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.

Update Google Cloud DNS provider Rrset.Get(name) method to return a list and change the `Rrset.List()` implementation to perform a paged walk
Some federated service e2e tests and a few ingress tests would become flaky after a few hundred runs. @csbell spent quite a lot of time debugging this and found out that this flakiness was due to a bug in the federated service controller deletion logic. Deletion of a federated service object triggers a logic in the controller to update the DNS records corresponding to that object. This DNS record update logic would return an error in failed runs which would in-turn cause the controller to reschedule the operation. This led to an infinite retry-failure cycle that never gave the API server a chance to garbage collect the deleted service object.
A couple of days ago we started seeing a correlation between the number of resource records in a DNS managed zone and these test failures. If you look at the test runs before and after run 2900 in the test grid - https://k8s-testgrid.appspot.com/cluster-federation#gce, you will notice that the grid became super green at 2900. That's when I deleted all the dangling DNS records from the past runs.
After some investigation yesterday, we found that `ResourceRecordSet.Get()` interface and its implementation, and `ResourceRecordSet.List()` implementation at least for Google Cloud DNS were incorrect.
This PR makes minimal set of changes (read: least invasive) in Google Cloud DNS provider implementation to fix these problems:
1. Modifies DNS provider Rrset.Get(name) interface to return multiple records and updates federated service controller.
There can be multiple DNS resource records for a given name. They can vary by type, ttl, rrdata and a number of various other parameters. It is incorrect to return a single resource record for a given name.
This change updates the Get interface to return multiple records for a given name and uses this list in the federated service controller to perform DNS operations.
2. Update Google Cloud DNS List implementation to perform a paged walk of lists to aggregate all the DNS records.
The current `List()` implementation just lists the DNS resorce records in a given managed zone once and retruns the list. It neither performs a paged walk nor does it consider the `page_token` in the returned response.
This change walks all the pages and aggregates the records in the pages and returns the aggregated list. This is potentially dangerous as it can blow up memory if there are a huge number of records in the given managed zone. But this is the best we can do without changing the provider interface too much.
Next step is to define a new paged list interface and implement it.

NONE
