Remove signal handler registration from pkg/kubelet
**What this PR does / why we need it**:
The goal of this change is to remove the registration of signal
handling from pkg/kubelet (i.e., library code).
If you register a signal handler in `main()` to aid in a controlled
and deliberate exit then the handler registered in `pkg/kubelet` often
wins and the process exits immediately. This means all other signal
handler registrations are currently racy if `DockerServer.Start()` is
directly or indirectly invoked.

**Special notes for your reviewer**:
This change also removes another signal handler registration from
`NewAPIServerCommand()`; a stop channel is now passed to this
function.

Measure scheduler throughput in density test
This is a step towards exposing scheduler-related metrics on [perf-dash](http://perf-dash.k8s.io/).
This particular PR adds scheduler throughput computation and makes the results available in our test artifacts.
So if you do some experiments, you'll have some historical baseline data to compare against.

Fix TestSchedulerWithVolumeBinding to avoid setting predicate ordering.
It is causing data race condition as predicate ordering is changing global
variable `predicatesOrdering`. Infact this test does not require any special
predicate order and should work on default predicate ordering as far as
VolumeScheduling feature is enabled.

It is pretty easy to reproduce this race by following these steps:
```
cd pkg/scheduler
go test -c -race
stress -p 100 ./scheduler.test

Predicate ordering to this unit test was added here: https://github.com/kubernetes/kubernetes/pull/57168
Since the whole scheduler instance uses just one ordering at time, not sure what is the advantage.

**What this PR does / why we need it**:
This PR sets the default seccomp profile of DNS addons to 'docker/default'. This PR is a followup of #62662. We are using 'docker/default' instead of 'runtime/default' in addons in order to handle node version skew. When seccomp profile is applied automatically by default later, we can remove those annotations.

Always masquerade node-originating traffic with a service VIP source ip
**What this PR does / why we need it**:
This is a follow up to make IPVS work on systems without cluster-cidr or masquerade-all.
On these systems the best matching network / source IP to reach the service VIP is the service VIP itself - at least for the host network.
The workaround is simple: Everything originating on the host (OUTPUT nat chain) with a source IP that is the VIP should be masqueraded.
The relevant rule change is the first rule in `KUBE-SERVICES`:
```
Chain KUBE-SERVICES (2 references)
pkts bytes target prot opt in out source destination
0 0 KUBE-MARK-MASQ all -- * * 0.0.0.0/0 0.0.0.0/0 match-set KUBE-CLUSTER-IP src,dst
104 6240 KUBE-MARK-MASQ tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp match-set KUBE-NODE-PORT-TCP dst
```
The matching rule could be stricter by matching src(ip),dst(ip),dst(port) but the src ip will only be selected if the VIP should be reached.
