s3_bucket always reports changed=true

[bluikko]

Summary

amazon.aws.s3_bucket always reports changed=true even when the bucket to create already exists.
This is with Ceph S3 in case that matters.

Looking at the issues this same problem has been reported in several modules. It might be a good idea to fix all the modules instead of one by one.
