Support Paths in roles

[ryanjfrizzell]

Some folks uses paths in their role naming convention. Ex: 'arn:aws:iam::584999999999:role/some/other/role/withSlashes'

AWS docs for role paths (https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_identifiers.html#identifiers-friendly-names)

the current code will fail with an error similar to this one if such role names are implemented.

Traceback (most recent call last):

    sys.exit(main())
