Detach/Attach custom policy to IAM user

[mazzy89]

I have noticed the following bug:

I've defined an IAM user which has attached to it a custom policy. Everytime I run the push I got the following result:

aws iam detach-user-policy --user-name foo --policy-arn arn:aws:iam::xxxxxxxxxxxxx:policy/my-custom-policy
aws iam attach-user-policy --user-name foo --policy-arn arn:aws:iam::xxxxxxxxxxxxx:policy/my-custom-policy

so basically a diff is detected even though there is no real diff
