Add support for iam_roles to Redshift

[dcosson]

Redshift somewhat recently added the ability to assign a list of IamRoles to a cluster, e.g. in the go sdk. This lets you specify the iam credentials of an s3 bucket or dynamodb table to COPY from in a role when you create the redshift cluster, so you don't need to pass them in to the COPY sql command.

Would be great for this to make it into terraform.

Hi @dcosson

Just a FYI, I have a PR open for this right now - it is a WIP as it requires 1 other PR to merge first :) It will make TF 0.7
