Example fails to build in us-gov-west-1

[cyorobert]

Hey, thanks for the hard work developing this project. I'm following along with https://ecsworkshop.com/platform/example/ and trying to get some infrastructure up and running on us-gov-west-1.

I've created the following configuration file:

mu.yml

---

environments:
  - name: acceptance
    provider: ecs
  - name: production
    provider: ecs
service:
    acceptance:
      disabled: true
    production:
      disabled: true

but receive the following error after running mu env up acceptance && mu env up production

ERROR    mu-{my-namespace}-iam-common:  CloudFormationRole (AWS::IAM::Role) CREATE_FAILED Partition "aws" is not valid for resource "arn:aws:iam::*:role/aws-service-role/ecs.amazonaws.com/AWSServiceRoleForECS*"

Is this an issue using Mu in govcloud, or an issue with my config?

looking at that error message, this makes me think that IAM behaves differently in govcloud than everywhere else:
Partition "aws" is not valid for resource

any chance you can swap to us-west-2 for educational purposes?

All the CloudFormation templates need to be updated to replace arn:aws with arn:${AWS::Partition}

fixed in #351
