Enhancement: Use module instance name for download directory

[MrMickS]

Using a build from master, with the code to download private modules from Terraform Cloud, I was able to get the following results from terrascan:

The scan works well but the File path is less helpful when it comes to working out which module inclusion has raised the issue.

It would be useful to have either the module name, or the module instance, as the path instead of the random unique value used.
