- All supported platforms can handle the same set of signals we're
interested in, thus we don't need build contraints to use a set of
signals on Linux, while restricting ourselves to only SIGINT on Darwin
and Windows.
- According to the documentation of os/signal, similar to SIGINT and
SIGTERM, SIGHUP causes the program to exit, therefore add it to the
list of handled signals.

fully qualify admission resources and kinds
Fully qualifies the `Kind` and `Resource` fields for admission attributes. The information was getting filtered at the `RESTHandler` before.

Update Docker version after cockpit installation
Fixes https://github.com/kubernetes/kubernetes/issues/24530
The vagrant setup didn't worked for me because `cockpit cockpit-kubernetes` brings their own Docker version (1.7) which doesn't work and the master components doesn't come up. More information about this bug are in my [issue](https://github.com/kubernetes/kubernetes/issues/24530).
My test system:
```bash
$ uname -a
Darwin MyMacBook.local 15.4.0 Darwin Kernel Version 15.4.0: Fri Feb 26 22:08:05 PST 2016; root:xnu-3248.40.184~3/RELEASE_X86_64 x86_64
$ vagrant --version

Update configmap design doc
1. Update ConfigMapSelector -> ConfigMapKeySelector
2. Update apiVersion to v1
3. Fix error validating data: expected type array, for field spec.containers[0].command, got string; if you choose to ignore these errors, turn validation off with --validate=false

Store node information in NodeInfo
This is significantly improving scheduler throughput.
On 1000-node cluster:
- empty cluster: ~70pods/s
- full cluster: ~45pods/s
Drop in throughput is mostly related to priority functions, which I will be looking into next (I already have some PR #24095, but we need for more things before).
This is roughly ~40% increase.
However, we still need better understanding of predicate function, because in my opinion it should be even faster as it is now. I'm going to look into it next week.

Do not update cache with so much effort
Fixes: #24298
1. Remove automatic update
2. Every time we check if we can get valid value from cache, if not, get the value directly from api

Add flag -t as shorthand for --tty
`-t` was deprecated in #12813 (Aug. 2015, about 6+ months ago).
Now remove `--template`'s shorthand `-t` and create a shorthand `-t` for `--tty` in `kubectl run`.

Add support for running clusters on GCI
Google Container-VM Image (GCI) is the next revision of Container-VM. See documentation at https://cloud.google.com/compute/docs/containers/vm-image/. This change adds support for starting a Kubernetes cluster using GCI.
With this change, users can start a kubernetes cluster using the latest kubelet and kubectl release binary built in the GCI image by running:
$ KUBE_OS_DISTRIBUTION="gci" cluster/kube-up.sh
Or run a testing cluster on GCI by running:
$ KUBE_OS_DISTRIBUTION="gci" go run hack/e2e.go -v --up
The commands above will choose the latest GCI image by default.

Switch from AllowAll to ABAC. All existing identities (that are created by deployment scripts) are given full permissions through ABAC. Manually created identities will need policies added to the `policy.jsonl` file on the master.

rkt: Add post-start hook support.
This adds a poll-and-timeout procedure after the pod is
started, to make sure the post-start hooks execute when the
container is actually running.
This is a temporal workaround for implementing post-hooks,
a long term solution is to use lifecycle event to trigger
those hooks, see https://github.com/kubernetes/kubernetes/issues/23084.
Also this fixes a bug of getting container ID for a non-running
container when running pre-stop hook.

Trusty: Add debug supports for docker and kubelet
This PR adds debug support in two aspects: (1) For a test cluster, docker command will have "--debug" flag. Recently we noticed that this is very helpful in debug e2e test failures; (2) The kubelet command line will be put in /etc/default/kubelet. If a developer wants to test kubelet flags without recreating a cluster, she/he only needs to revise this file and then run "initctl restart kubelet". In addition, this PR fixes a couple of small things like comments and alignment.
Test result:
(1) Manually verified changing /etc/default/kubelet and run "initctl restart kubelet";
(2) Verified docker command line flag "--debug";
(3) e2e on pure trusty cluster and hybrid cluster all passed.
@roberthbailey @dchen1107 @zmerlynn please review it.

Add kubelet flags for eviction threshold configuration
This PR just adds the flags for kubelet eviction and the associated generated code.
I am happy to tweak text, but we can also do that later at this point in the release.
Since this causes codegen, I wanted to stage this first.
