Merge pull request #3210 from KashifSaadat/feature-gate-strict-iam-policies

Automatic merge from submit-queue

Allow the strict IAM policies to be optional

The stricter IAM policies could potentially cause regression for some edge-cases, or may rely on nodeup image changes that haven't yet been deployed / tagged officially (currently the case on master branch since PR https://github.com/kubernetes/kops/pull/3158 was merged in).

This PR just wraps the new IAM policy rules around a cluster spec flag, `EnableStrictIAM`, so will default to the original behaviour (where the S3 policies were completely open). Could also be used to wrap PR https://github.com/kubernetes/kops/pull/3186 if it progresses any further.

- Or we could reject this and have the policies always strict! :)
