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

If a check is marked with type "skip", it will be marked as Info.

Support scored property:
If a check is not scored and is not marked with type skip, it will be marked as Warn.

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

Changes to the json structure and field names

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.

Results of manual checks are forced to WARN to inform users to check manually.

Results of manual checks are forced to WARN to inform users to check manually.

Issue #17.

This is caused by a command in the audit pipeline (for example
ps -ef | grep kube-apiserver) failing. The causes of this failure
in my testing is usually a missing config file.

Extensive refactor and correction in verification code to check for
config files and binaries.

Replace joncalhoun/pipes with implementation using exec.Cmds so errors
are visible and can be handled when audit pipeline commands fail.

Change some audit commands
from: ps -ef | grep <cmd> | grep -v
to:   ps -C <something> -o comm,args --no-headers

which is simpler to work with.

Use the same format output for warnings even if they aren’t related to
a specific test ID

* Replace the default help text

* Readme file, including the test config format documentation

* Typo

* Warn if config files / executables aren't found

* Ignore original name of executable (as per current README)

* Update tests to avoid failing on stat of a non-existant file

* Add a makefile for ease of build
