fix #280

This is useful for checking values in YAML (possibly JSON) kubernetes config files.

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.

Tests could easily be marked "skip" because the user doesn't want to run them in their environment, and in this common case the set of tests will be non-nil

This commit adds the actual value of the result
of the value which was returned by the test.

and modify text to command function to support this.

Shell builtins fail the binary command lookup test which result in a
WARN. Audit commands which include shell builtins must use the form:

   "/bin/sh -c 'sh-builtin arg'"

So they are executed properly. Additionally Go will fail to execute
commands involving shell builtins if they are not in the above format.
