aggregate cluster roles

I added
```yaml
aggregationRule:
clusterRoleSelectors:

3. Pass parameters needed by `FakeDockerClient` thru `ClientConfig` to dockershim
(TODO, the second part) Make dockershim tolerate when dockerd is down, otherwise it will still fail kubelet
Please note after this PR, kubelet will still fail if dockerd is down, this will be fixed in the subsequent PR by making dockershim tolerate dockerd failure (initializing docker client in a separate goroutine), and refactoring cgroup and log driver detection.

Default Go HTTP transport does not allow to use CIDR notations in
NO_PROXY variables, thus for certain HTTP calls that is done inside
kubeadm user needs to put explicitly multiple IP addresses. For most of
calls done via API machinery it is get solved by setting different Proxy
resolver. This patch allows to use CIDR notations in NO_PROXY variables
for currently all other HTTP calls that is made inside kubeadm.

Move core API to pkg/apis/core
Fixes https://github.com/kubernetes/kubernetes/issues/55304.
This moves the types in pkg/api and most of pkg/api/v1 to pkg/apis/core to match the other api groups, following-up on what https://github.com/kubernetes/kubernetes/pull/44784 did for the external types.
It's a nearly 100% mechanical package move with a number of trivial fixups in code-generators and in tests which do string comparisons of types via reflection.
**Most importantly:**
- group names are unchanged
- apimachinery semantics are unchanged
- the outside api is unchanged.
Note that some packages for helpers are left in pkg/api/v1. Splitting them into helpers which belong tightly to the api and those which are not is left to follow-ups.
