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."
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.
