Ambiguous verify variable

[daviddavis]

The repoaudit code has this verify variable that I believe is used to control whether to verify the ssl cert when making url requests. We should:

1. Better document this variable as I was unclear what it was used for
2. Expose it via the CLI so users can use it
3. It would be nice to somehow set it globally instead of passing it around from function to function. Maybe we could set up a single session and reuse it whenever making requests
