add fulljson formatter

[arlimus]

This is a separate formatter which will always include all information on controls. For regular json runs this is most likely too noisy.

inspec exec example/profile --format fulljson

snips from example output:

  "examples": [
    {
      "id": "tmp-1.0",
      "title": "Create /tmp directory",
      "desc": "An optional description...",
      "code": "control \"tmp-1.0\" do                        # A unique ID for this control\n  impact 0.7                                # The criticality, if this control fails.\n  title \"Create /tmp directory\"             # A human-readable title\n  desc \"An optional description...\"         # Describe why this is needed\n  ref \"Document A-12\", url: 'http://...'    # Additional references\n\n  describe file('/tmp') do                  # The actual test\n    it { should be_directory }\n  end\nend\n",
      "impact": 0.7,
      "status": "passed",
      "code_desc": "File /tmp should be directory",
