Update openshift executable config

Clean up OCP benchmark config.

add new config files from the new CIS Kubernetes Benchmark

The OCP benchmarks uses configs for only binary component variable names.
This commit cleans up the OCP config by removing all configuration
except those component binaries required to run kube-bench on OCP
installations and adds missing ones.

Fix the start from 1.11 to 1.13 and adding changes from pull #227, and pull #228.

replace with the new node.yaml file

Fix issues with checks for kubelet configuration files

Only find flags on the process we really want

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.
