Proposal: Create a terrascan wrapper with argument validation

[jason-tyler]

Use a wrapper to allow clients to invoke Terrascan with arguments.

Example: https://github.com/jason-tyler/terrascan/tree/feature/main_args

If you agree with this method, create a "feature/main_args" branch and I'll PR a start at this into your repo.

Definitely. I thought of doing this eventually, but didn't had time to get to it. What I like about this is that we can swap out the dependency on python unittest at some point without affecting the way you execute terrascan.

[jason-tyler]

Good point. I'll submit a PR after you create the 'feature/main_args' branch in your repo.
