92df9cb36c Read kubernetes version from environment (#390) 
* 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

a88b0703d8 Add kubeconfig variable substitution for kubelet and proxy. 
There are checks for the kubeconfig for both kubelet and proxy which
the current kube-bench implementation does not check for properly.
kube-bench checks the wrong files.

This PR adds support for variable substitution for all the config file
types are that should be checked in the CIS benchmarks.

This PR also fixes a buggy in CIS 1.3.0 check 2.2.9, which checks for
ownership of the kubelet config file /var/lib/kubelet/config.yaml but
recommends changing ownership of kubelet kubeconfig file
/etc/kubernetes/kubelet.conf as remediation.

ed21839464 Add getServiceFiles function. 
The CIS benchmark check for node checks 2 config files for kubelet:
  - kubelet config file (kubelet.conf)
  - kubelet systemd unitfile (10-kubeadm.conf)

The getServiceFiles function gets candidates for kubelet systemd
unitfile and returns valid untifiles.

39d94df81b Add tip about the --version flag to error output 
If people are trying to use the Docker image to check their cluster, there's a
big likelyhood of them hitting the error message saying that either `kubectl`
or `kubelet` need to be found in order for `kube-bench` to be able to determine
the Kubernetes version in use.

This adds a tip that the version can be specified manually with the `--version`
flag which is a lot easier than having to make a new Docker image with the
right version of `kubelet`/`kubectl` in order for `kube-bench` to work.
