Set default bucket encryption during bucket creation

All S3 buckets have encryption configured by default,
and objects are automatically encrypted by using server
side encryption. When we do get-bucker-encryption on
any bucket we get the the default encryption configuration.

With this patch we set default encryption on bucket while
creating the bucket and follow the behavior of S3 bucket.
