Inode Eviction Test is Flaky

This Pull Request:
Marks the InodeEviciton test as flaky
Increases the timeout for disk pressure because coreos has nearly 2 million inodes.
Decreases the status polling interval so we can see eviction ordering better.

Curating Owners: pkg/runtime

cc @lavalamp @smarterclayton @deads2k @caesarxuchao

In an effort to expand the existing pool of reviewers and establish a
two-tiered review process (first someone lgtms and then someone
experienced in the project approves), we are adding new reviewers to
existing owners files.


If You Care About the Process:
------------------------------

We did this by algorithmically figuring out who’s contributed code to
the project and in what directories.  Unfortunately, that doesn’t work
well: people that have made mechanical code changes (e.g change the
copyright header across all directories) end up as reviewers in lots of
places.

Instead of using pure commit data, we generated an excessively large
list of reviewers and pruned based on all time commit data, recent
commit data and review data (number of PRs commented on).

At this point we have a decent list of reviewers, but it needs one last
pass for fine tuning.

Also, see https://github.com/kubernetes/contrib/issues/1389.

TLDR:
-----

As an owner of a sig/directory and a leader of the project, here’s what
we need from you:

1. Use PR https://github.com/kubernetes/kubernetes/pull/35715 as an example.

2. The pull-request is made editable, please edit the `OWNERS` file to
remove the names of people that shouldn't be reviewing code in the
future in the **reviewers** section. You probably do NOT need to modify
the **approvers** section. Names asre sorted by relevance, using some
secret statistics.

3. Notify me if you want some OWNERS file to be removed.  Being an
approver or reviewer of a parent directory makes you a reviewer/approver
of the subdirectories too, so not all OWNERS files may be necessary.

4. Please use ALIAS if you want to use the same list of people over and
over again (don't hesitate to ask me for help, or use the pull-request
above as an example)

Significantly speed-up make

- do not call `dirname` for every go file => gives **>8 seconds** on each make run
- do not preserve time during rsync from `_output/local/go/bin` to `_output/local/bin/<os>/<arch>`:
  
  We do a touch after our rebuild heuristic triggers.
  
  If in `_output/local/go/bin` you have an older binary and go decides that it's good enough, the following rsync will "preserve the timestamp" of the binary copy in `_output/local/bin/<os>/<arch>`. This reverts the effect of any previous `touch` (compare `Makefile.generated_files`).

  We do a complete rsync of binaries for each go target, not only the one which is rebuilt. This means that later go targets will overwrite the timestamps of freshly touched binaries. Hence, our rebuild heuristic will trigger again and again when running `make`.

  This PR remove the "preserve mtime" from the rsync call. Hence, the effect of touch is not reverted anymore by later rsyncs.

Add a package for handling version numbers (including non-"Semantic" versions)

As noted in #32401, we are using Semantic Version-parsing libraries to parse version numbers that aren't necessarily "Semantic". Although, contrary to what I'd said there, it turns out that this wasn't actually currently a problem for the iptables code, because the regexp used to extract the version number out of the "iptables --version" output only pulled out three components, so given "iptables v1.4.19.1", it would have extracted just "1.4.19". Still, it could be a problem if they later release "1.5" rather than "1.5.0", or if we eventually need to _compare_ against a 4-digit version number.

Also, as noted in #23854, we were also using two different semver libraries in different parts of the code (plus a wrapper around one of them in pkg/version).

This PR adds pkg/util/version, with code to parse and compare both semver and non-semver version strings, and then updates kubernetes to use it everywhere (including getting rid of a bunch of code duplication in kubelet by making utilversion.Version implement the kubecontainer.Version interface directly).

Ironically, this does not actually allow us to get rid of either of the vendored semver libraries, because we still have other dependencies that depend on each of them. (cadvisor uses blang/semver and etcd uses coreos/go-semver)

add QoS pod status field

Right now, applications retrieving pod information must reimplement the QoS classification logic on the client side if they wish to know the QoS class of the pod.

The PR adds the QoS class to the pod status so it can be used directly by clients.

This is a step toward addressing #33255

Set --anonymous-auth to false on v1.5 clusters to preserve the locked-down v1.4 behaviour

From discussions with sig-auth-people.

Without this patch, anyone can do basically anything, because the apiserver in v1.5 mode is unprotected due to that kubeadm doesn't have any ABAC/RBAC-authorizers.

Removes `cluster/mesos` which has been subsumed by https://github.com/kubernetes-incubator/kube-mesos-framework. As `@karlkfi` is the only maintainer listed in an `OWNERS` file and taking into account https://github.com/kubernetes/kubernetes/issues/38392, this code is dead and should be removed.

controller: adopt pods only when controller is not deleted

On kubemark master, kubelet now runs as a supervisord process and all master components as pods

This PR fixes issue #37485
On kubemark, previously we had a custom setup that runs master components as top-level processes under supervisord, which is lighter than running kubelet and docker.
This PR makes kubelet run as a process under supervisord and the master components (apiserver, controller-manager, scheduler, etcd) as pods, making testing on kubemark mimic real clusters better.
Also, start-kubemark-master.sh now closely resembles cluster/gce/gci/configure-helper.sh, allowing easy integration in future.

Fix leaking goroutines in watch cache

Fixes #38670 which causes leaked goroutines in the API server. The root cause is: if the WatchServer timeout [fires](https://github.com/kubernetes/kubernetes/blob/master/pkg/apiserver/watch.go#L187-L188) when the `result` channel is full, `sendWatchCacheEvent` will be blocked on the write to the `result` even though `cacheWatch.Stop()` is [called](https://github.com/kubernetes/kubernetes/blob/master/pkg/apiserver/watch.go#L171), because WatchServer stops consuming the `result` channel after the timeout.
Thanks to @krousey for identifying the problem. cc @mml @yujuhong
