more explicit requirements for pre-commit hook
I don't know if using the pre-commit hook is still a best-practice, but godep and etcd are requirements for it to succeed.

Refactored SeedProvider and Updated Docker
This is a redo of the last PR that I munged 😄
- fixed maven build folder structure
- updated build to C* 3.4
- refactored Seed Provider - improved error handling, updated default SeedProvider code
- added start of unit tests. Not as comprehensive as I would like
- updated docker image to debian:jessie
- installed openjdk 8
- added some docker fu to make the image smaller
- updated docker to C* 3.4 and update yaml
- updated README content. Added a section about the docker, and the SeedProvider
Have not had a chance to test the docker on k8s, because I do not have a local docker repo.
NOTE: someone needs to push the docker image into the google repo. Not sure what the process is ... I will submit another PR request with changes to the yaml files.

Provide flags to use etcd3 backed storage
ref: #24405
What's in this PR?
- Add a new flag "storage-backend" to choose "etcd2" or "etcd3". By default (i.e. empty), it's "etcd2".
- Take out etcd config code into a standalone package and let it create etcd2 or etcd3 storage backend given user input.

- 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.

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

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
