Fix faulty assumptions in summary API testing
**What this PR does / why we need it**:
1. on systemd, launch kubelet in dedicated part of cgroup hierarchy
1. bump allowable memory usage for busy box containers as my own local testing often showed values > 1mb which were valid per the memory limit settings we impose
1. there is a logic flaw today in how we report node.memory.stats that needs to be fixed in follow-on.
for the last issue, we look at `/sys/fs/cgroup/memory.stat[rss]` value which if you have global accounting enabled on systemd machines (as expected) will report 0 because nothing runs local to the root cgroup. we really want to be showing the total_rss value for non-leaf cgroups so we get the full hierarchy of usage.

Loosen requirements of cluster logging e2e tests, make them more stable
There should be an e2e test for cloud logging in the main test suite, because this is the important part of functionality and it can be broken by different components.
However, existing cluster logging e2e tests were too strict for the current solution, which may loose some log entries, which results in flakes. There's no way to fix this problem in 1.6, so this PR makes basic cluster logging e2e tests less strict.

[Federation] Rewrite ReplicaSet CRUD and Preferences tests.
I think `should create replicasets and rebalance them` test is still flaky. I still don't know the source of this flakiness. I will continue hunting. But it is a lot less flaky than before (or perhaps it even never passed before?). This PR could be merged now and flake hunting can happen in parallel.

Use storage.k8s.io/v1 in tests instead of v1beta1
This is trimmed version of #42477 and contains only tests of the new storage API. Together with #43285 it passes all dynamic provisioning tests on my GCE.
I did not change vsphere_utils.go and vsphere_volume_diskformat.go as @divyenpatel runs master vsphere tests with Kubernetes 1.5 - @divyenpatel, did I get it right?

kubectl: Use v1.5-compatible ownership logic when listing dependents.
**What this PR does / why we need it**:
This restores compatibility between kubectl 1.6 and clusters running Kubernetes 1.5.x. It introduces transitional ownership logic in which the client considers ControllerRef when it exists, but does not require it to exist.
If we were to ignore ControllerRef altogether (pre-1.6 client behavior), we would introduce a new failure mode in v1.6 because controllers that used to get stuck due to selector overlap will now make progress. For example, that means when reaping ReplicaSets of an overlapping Deployment, we would risk deleting ReplicaSets belonging to a different Deployment that we aren't about to delete.
This transitional logic avoids such surprises in 1.6 clusters, and does no worse than kubectl 1.5 did in 1.5 clusters. To prevent this when kubectl 1.5 is used against 1.6 clusters, we can cherrypick this change.

The test blindly checked all "pause" processes on the node, assuming
they were all infra containers. This change takes a snapshot of all
existing "pause" processes on the node, and exclude them in the
validation. The test still relies on the fact that it runs exclusively
on the node. If that assumption changes, we will need other methods to
locate the PIDs of the infra containers.
In particular, we should not assume ControllerRefs are necessarily set.
However, we can still use ControllerRefs that do exist to avoid
interfering with controllers that do use it.

Add guards for StatefulSet and AppArmor upgrade testing
This PR adds automated upgrade infrastructure to allow test suites to know what versions and node images are going to be testing and whether or not they should be skipped. It also adds a guard to prevent StatefulSets from being tested with versions prior to 1.5.0, and a guard to prevent AppArmor from running on distros other than gci and ubuntu.

Fix Deployment upgrade test.
**What this PR does / why we need it**:
When the upgrade test operates on Deployments in a pre-1.6 cluster (i.e. during the Setup phase), it needs to use the v1.5 deployment/util logic. In particular, the v1.5 logic does not filter children to only those with a matching ControllerRef.
