* 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
* testing Azure config locations
* "Updated default config.yaml to incorporate Azure AKS file locations for kubelet"
* "Adjusted order of new lines. Removed unneeded lines."
* 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
* Update master.yaml
* Update node.yaml
Fix 2.1.11 - got DEPRECATED
2.1.14 changed to be a set of options, would be fixed by https://github.com/aquasecurity/kube-bench/pull/367
* Update master.yaml
* Update node.yaml
change 2.1.11 Title, and state to not scored
* issue #344: Adds support for array comparison. Every element in the source array must exist in the target array.
* issue #344: Fixed typo and found if condition based on code review
* adds unit tests for valid_elements comparison
* removes spaces from split strings
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:5e6cdfd 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:5e6cdfd master -v 1

If kube-controller-manager is getting detected by older versions of
procps, it will only be detected if we're looking for kube-controller
(15 chars)
NOTE: "The command name is not the same as the command line. Previous versions of
procps and the kernel truncated this command name to 15
characters. This limitation is no longer present in both. If
you depended on matching only 15 characters, you may no longer
get a match."
This improves the TestControls_RunChecks() test by making
more comprehensive assertions on a more fully fledged input yaml
