retry spot instance creation when an "Invalid IAM Instance Profile name" error pops up (#9810)
PutRolePolicy & AddRoleToInstanceProfile are eventually consistent but it is not possible to wait for them to be done here: 0785c2f6fc/builder/amazon/common/step_iam_instance_profile.go (L117-L134) which was causing the `CreateFleet` to fail (100% for me). So for now we retry a bit later. Waiting 5 seconds after the previously linked code also fixed this.
