* changes are per PR review

* docs: Clarify the meaning of WARN state

* Update README.md

* removed version prior to 1.11

* removed references to kubernetes versions prior to 1.11

Strictly, we don't have the changes in 1.13-json but we do have them in 1.13

* Read kubernetes version from environment

Set kubernetes version to the value of the environment variable `KUBE_BENCH_VERSION` if it is defined and the flag `--version` is not specified on the kube-bench command line.

The command line flag `--version` takes precedence of the environment variable `KUBE_BENCH_VERSION` if both are defined.

* Add info about KUBE_BENCH_VERSION to README

* Remove duplicate documentation.

* Add test configuration header back in main README.

* Add missing regex operator in docs/README.

* Fix incorrect description of configuration options bins, confs etc.

* Move description of version auto-detection to main README.

* Use 1.13 in examples since cfg/1.12 doesn't exist

* Remove duplicate sentence about regex

This sentence is now in the docs/README

* Add link to the docs for test YAML definitions

Without passing in kubeconfig credentials:

```bash
$ docker run --pid=host -v /etc:/etc:ro -v /var:/var:ro -v $(which kubectl):/usr/bin/kubectl -t lizrice/kube-bench:5e6cdfdb master -v 1

```
As updated in the README with this fix:

```bash
docker run --pid=host -v /etc:/etc:ro -v /var:/var:ro -v $(which kubectl):/usr/bin/kubectl -v ~/.kube:/.kube -e KUBECONFIG=/.kube/config -t lizrice/kube-bench:5e6cdfdb master -v 1

Add pull requests section
Include instructions for kube-bench version
Other small wording changes

Because we don’t want to put people off running kube-bench altogether in these environments

Values in the version-specific files override the main file

Also describe how tests can be omitted by editing the YAML

Support new configuration options besides --flags:
- JSON file through `jsonpath`
- YAML file through `yamlpath`

These new options are fully backwards-compatible with the existing
tests.

Added a new profile, 1.11-json, that expects a JSON kubelet
configuration file and scores accordingly. This profile is compatible
with EKS.

The root command will run node checks and if possible master checks.
I've also added some Makefile targets to improve local testing and improve the documentation.
