Adam Leff dfce561276 Provide better error message when inspec.yml is invalid
Currently, if the inspec.yml for a profile is invalid (such as including
an improperly-defined multi-line string), InSpec will throw an exception
from the YAML parser that does not given a clear indication that the
issue was encountered while parsing the inspec.yml file.

This change introduces a better exception message to clue the user into
where the problem actually lies.
