HPA: Consider unready pods separately
**Release note**:
``` release-note
The Horizontal Pod Autoscaler now takes the readiness of pods into account when calculating desired replicas.
```
Currently, the HPA considers unready pods the same as ready pods when
looking at their CPU and custom metric usage. However, pods frequently
use extra CPU during initialization, so we want to consider them
separately.
This commit causes the HPA to consider unready pods as having 0 CPU
usage when scaling up, and ignores them when scaling down. If, when
scaling up, factoring the unready pods as having 0 CPU would cause a
downscale instead, we simply choose not to scale. Otherwise, we simply
scale up at the reduced amount calculated by factoring the pods in at
zero CPU usage.
Similarly, if we are missing metrics for any pods, those pods will be
considered as having 0% CPU when scaling up, and 100% CPU when
scaling down. As with the unready pods calculation, this cannot change
the direction of the scale.
The effect is that unready pods cause the autoscaler to be a bit more
conservative -- large increases in CPU usage can still cause scales,
even with unready pods in the mix, but will not cause the scale factors
to be as large, in anticipation of the new pods later becoming ready and
handling load.

This will print, e.g.:
```

name: "e2e-test-mtaufen-minion-group-jo79", osImage: "Debian GNU/Linux 7 (wheezy)", kubeletVersion: "v1.4.5-beta.0.45+90d209221ec8dc-dirty"
name: "e2e-test-mtaufen-minion-group-ox5l", osImage: "Debian GNU/Linux 7 (wheezy)", kubeletVersion: "v1.4.5-beta.0.45+90d209221ec8dc-dirty"

Node Conformance Test: Containerize the node e2e test
For #30122, #30174.
Based on #32427, #32454.
**Please only review the last 3 commits.**
This PR packages the node e2e test into a docker image:
- 1st commit: Add `NodeConformance` flag in the node e2e framework to avoid starting kubelet and collecting system logs. We do this because:
- There are all kinds of ways to manage kubelet and system logs, for different situation we need to mount different things into the container, run different commands. It is hard and unnecessary to handle the complexity inside the test suite.
- 2nd commit: Remove all `sudo` in the test container. We do this because:
- In most container, there is no `sudo` command, and there is no need to use `sudo` inside the container.
- It introduces some complexity to use `sudo` inside the test. (https://github.com/kubernetes/kubernetes/issues/29211, https://github.com/kubernetes/kubernetes/issues/26748) In fact we just need to run the test suite with `sudo`.
- 3rd commit: Package the test into a docker container with corresponding `Makefile` and `Dockerfile`. We also added a `run_test.sh` script to start kubelet and run the test container. The script is only for demonstration purpose and we'll also use the script in our node e2e framework. In the future, we should update the script to start kubelet in production way (maybe with `systemd` or `supervisord`).

Adding cadcading deletion support for federated secrets
Ref https://github.com/kubernetes/kubernetes/issues/33612
Adding cascading deletion support for federated secrets.
The code is same as that for namespaces. Just ensuring that DeletionHelper functions are called at right places in secret_controller.
Also added e2e tests.

```release-note
federation: Adding support for DeleteOptions.OrphanDependents for federated secrets. Setting it to false while deleting a federated secret also deletes the corresponding secrets from all registered clusters.
```
Currently, the HPA considers unready pods the same as ready pods when
looking at their CPU and custom metric usage. However, pods frequently
use extra CPU during initialization, so we want to consider them
separately.
This commit causes the HPA to consider unready pods as having 0 CPU
usage when scaling up, and ignores them when scaling down. If, when
scaling up, factoring the unready pods as having 0 CPU would cause a
downscale instead, we simply choose not to scale. Otherwise, we simply
scale up at the reduced amount caculated by factoring the pods in at
zero CPU usage.
The effect is that unready pods cause the autoscaler to be a bit more
conservative -- large increases in CPU usage can still cause scales,
even with unready pods in the mix, but will not cause the scale factors
to be as large, in anticipation of the new pods later becoming ready and
handling load.
Similarly, if there are pods for which no metrics have been retrieved,
these pods are treated as having 100% of the requested metric when
scaling down, and 0% when scaling up. As above, this cannot change the
direction of the scale.
This commit also changes the HPA to ignore superfluous metrics -- as
long as metrics for all ready pods are present, the HPA we make scaling
decisions. Currently, this only works for CPU. For custom metrics, we
cannot identify which metrics go to which pods if we get superfluous
metrics, so we abort the scale.

The e2e tests cover cases like cluster size changed, parameters
changed, ConfigMap got deleted, autoscaler pod got deleted, etc.
They are separated into a fast part(could be run parallelly) and
a slow part(put in [serial]). The fast part of the e2e tests cost
around 50 seconds to run.
