Add evidences to Compliance Finding (#1157)

When reporting Compliance Finding, we want to specify which File, API or
Device caused us to trigger the finding. For example, if we have a
terraform file which creates an AWS ec2 instance with public 22 port, we
want to point to the file where we found the issue.

#### Description of changes:
* Add evidences to Compliance Finding
