Add warn reason (#547)

* Update check.go

Added new warn_reason value which gives a brief explanation about why the not scored tests failed

* Update common.go

Changed when a not scored test fails because it has a wrong syntax audit command or just running something that can't be run the print the failure. but if the test just fails because it doesn't line up with the cis hardening recommendations then print the remediation text.

* Update check/check.go

fix typo
