The RGW support server side encryption with help of s3 protocol, till now the `sse:kms` was support in which keys will be provided by the user and but it will be saved in external management service like vault. Now the support for `sse:s3` is added so the entire encryption key management is performed by RGW itsels. Signed-off-by: Jiffin Tony Thottan <thottanjiffin@gmail.com>
