* Fedora stores its kernel configs in /usr/lib/modules/$(uname -r)
* Fedora/CentOS/RHEL atomic hosts use /usr/lib/ostree-boot, though this location is deprecated
* The lack of these locations in the validator is causing kubeadm to hang on "failed to parse kernel config" in its preflight checking on fedora and atomic host

Add a new API version apps/v1beta2
xref: #49135
This PR adds a new API version `apps/v1beta2` which contains a copy (of types, conversions, and defaults) of `apps/v1beta1` StatefulSet, Deployment, and their subresources. Note that `apps/v1beta2` is still WIP and we will make breaking changes to it before releasing 1.8.
Moving core controllers (StatefulSet, Deployment, ReplicaSet, DaemonSet) to `apps/v1beta2` is the first step of moving them to `apps/v1` (GA).
This PR is a starting point for DaemonSet and ReplicaSet to move from `/extensions` to `/apps` and for Deployment and StatefulSet to make some breaking changes (e.g. new defaults and/or remove deprecated fields).

Reduce hollow proxy mem/node
As likely expected, kubemark-scale failed to even start with n1-standard-8 nodes. Because 1/3rd of our hollow nodes didn't even get scheduled due to their requests:
```
I0720 17:45:08.139] Found only 3325 ready hollow-nodes while waiting for 5000.
I0720 17:45:20.435] 3326 hollow-nodes are reported as 'Running'
I0720 17:45:20.442] 1675 hollow-nodes are reported as NOT 'Running'
```
If we want to experiment with smaller nodes anyway, then this change is needed. Though we most likely will end up OOM'ing.
Explanation for new value:
We have 62.5 hollow-node / real-node
=> mem available per hollow node = 30GB / 62.5 = 480MB
minus 100MB (kubelet)
minus 20MB (npd)
=> 360MB for proxy should be = 100MB + 5000*(mem/node)
=> 50KB mem/node (with some slight slack)

Test Ubuntu image using GKE image spec on master
Ref: https://github.com/kubernetes/kubernetes/issues/46891
This PR changes the files referenced in test-infra for running Ubuntu image tests against GKE system spec on master.
The two properties files are shared by the tests against all k8s branches but the `SYSTEM_SPEC_NAME` is only available on master. This should be fine because the tests in the non master branches will just ignore the unknown env variable.
