JAS scan - return scanner result when applicability is false

[yannc21]

Is your feature request related to a problem? Please describe.
When running jf docker scan <imageName>:<imageTag> --format=simplejson, we do get the applicability for a CVE and when it's false, we might want to return the reason of the "non applicability"

Describe the solution you'd like to see
As behind the scene, we're calling the Xray api GET /api/v1/scan/graph/<scanID>?include_vulnerabilities=true which returns a field info that we should return as well

here is the result of the Xray api :

{
  "artifacts": [
    { ...},
      "issues": [
        {
          "issue_id": "XRAY-607947",
           ...    
          "applicability": [
            {
              "scanner_available": true,
              "component_id": "docker://webapi:1.0.1-alpine",
              "source_comp_id": "alpine://3.8:zlib:1.2.11-r1",
              "cve_id": "CVE-2018-25032",
              "scan_status": 1,
              "applicability": false,
              "scanner_explanation": "<p>The scanner checks whether the vulnerable function <code>deflateInit2</code> is called.</p>", 
              "evidence": null,
              "info": "The vulnerable function deflateInit2 is never called",
              "details": null
            }
          ],

We could improve the current response of the jf docker scan with a new attribute called scannerResult in vulnerabities[*].cves[*].applicability

{
  "vulnerabilities": [
    {
      "severity": "High",
      "impactedPackageName": "3.8:zlib",
      "impactedPackageVersion": "1.2.11-r1",
      "impactedPackageType": "Alpine",
      "components": [
        {
          "name": "sha256__d9ff549177a94a413c425ffe14ae1cc0aa254bc9c7df781add08e7d2fba25d27.tar",
          "version": ""
        }
      ],
      "summary": "zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches.",
      "applicable": "Not Applicable",
      "fixedVersions": [
        "[1.2.11-r4]"
      ],
      "cves": [
        {
          "id": "CVE-2018-25032",
          "cvssV2": "5.0",
          "cvssV3": "7.5",
          "applicability": {
            "status": "Not Applicable",
            "scannerDescription": "The scanner checks whether the vulnerable function `deflateInit2` is called."
            "scannerResult": "The vulnerable function deflateInit2 is never called",
          }
        }
      ],
    }
   ]

We would need to update the Applicability struct and set the info field in the GetCveApplicabilityField()
