network/cni: Unconditionally bring up `lo` interface
This is already done in kubenet. This specifically fixes an issue where a kubelet-managed network for the rkt runtime does not have an "UP" lo interface.
Fixes#28561
If this fix doesn't seem right, it could also be implemented by rkt effectively managing two "cni" network plugins, one for the user requested network, one for lo.
Followup CRs can improve unit testing further and then possibly remove the vendor directory logic (which seems like dead code)

Kubelet: Pod level Resource Management
This proposal outlines our plan for improving resource management in Kubernetes by having a Cgroup hierarchy with QoS and Pod level Cgroups.
This is the initial proposal which broadly covers our goals and how we plan to achieve it. At this point we would really appreciate feedback from the community.
This is tied to the upstream issue #5671. So i would request
@vishh @dchen1107 @bgrant0607 @jdef PTAL.
[]()
- what the test is doing
- how the test is set up
- subsections of the test setup
additional output
- print time spent getting ready to run proxy attempts
- number of test cases
- multiple attempts of each test case
- how many total proxying attempts will be made
- fast path output now has numerical identity of attempt like error output
- error output has time taken and http status like fast path output
batching runs
- run groups of test cases vs starting all 34*20=680 proxy attempts at
the same time.
- don't wait between starting proxy attempts anymore.
proxy e2e changes
- disable the client side rate limiter
- use `By` construct of ginkgo for inline `STEP` logging
- move the waitGroup add outside of the loop

TestLoadBalancer() test v1 not v2
TestLoadBalancer() should test v1 and TestLoadBalancerV2() test v2, but In TestLoadBalancerV() there are codes:
cfg.LoadBalancer.LBVersion = "v2"

Give the complete and correct path to client/kubectl/apiserver related
for client/kubectl, “client/unversioned","kubectl/describe.go","kubectl/stop.go", it is not easy to find the location, better add "pkg/".
for apiserver, "registry/daemon", also better add "pkg/", and daemon not exists, should be "daemonset".

Remove duplicate prometheus metrics
This was a relic from before Kubernetes set Docker labels properly. Cadvisor now properly exposes the Docker labels (e.g. `io.kubernetes.pod.name` as `io_kubernetes_pod_name`, etc) so this is no longer required & actually results in unnecessary duplicate Prometheus labels.

cleanup wrong naming: limitrange -> hpa
The code is in `horizontalpodautoscaler/strategy.go`, but the parameter is "limitrange". This is legacy copy-paste issue...

make addition group RESTStorage registration easier
Starts factoring out `RESTStorage` creation to eventually allow for decoupled API group `RESTStorage` configuration.
Right now you can't add additional groups without modifying the main API Group registration in master.go. Allows the `master.Config` to hold a function that can build a `RESTStorage` based on the `Master` struct.

Validation logic applied to edited file
The file that is submitted via ``edit`` is now subject to validation
logic as any other file. The validation flags were added to the ``edit``
command.
Fixes: #17542
Also allow a new AcceptContentTypes field to allow the client to ask for
a fallback serialization when getting responses from the server. This
allows a new client to ask for protobuf and JSON, falling back to JSON
when necessary.
The changes to request.go allow error responses from non-JSON servers to
be properly decoded.

rkt: Fix /etc/hosts /etc/resolv.conf permissions
#29024 introduced copying /etc/hosts and /etc/resolv.conf before mounting them into rkt containers. However, the new files' permissions are set to 0640, which make these files unusable by any other users than root in the container as shown below. This small patch changes the permissions to 0644, as typically set.
```
# host rabbitmq
rabbitmq.default.svc.cluster.local has address 10.3.0.211
# ls -la /etc/resolv.conf
-rw-r-----. 1 root root 102 Jul 23 13:20 /etc/resolv.conf
# sudo -E -u foo bash
$ cat /etc/resolv.conf
cat: /etc/resolv.conf: Permission denied
$ host rabbitmq
;; connection timed out; no servers could be reached
# exit
# chmod 0644 /etc/resolv.conf /etc/hosts
# sudo -E -u foo host rabbitmq
rabbitmq.default.svc.cluster.local has address 10.3.0.211

Eviction manager needs to start as runtime dependent module
To support disk eviction, the eviction manager needs to know if there is a dedicated device for the imagefs. In order to know that information, we need to start the eviction manager after cadvisor. This refactors the location eviction manager is started.
