The Copy object is a simple call to Ozone Manager. This API can only be done after the PUT OBJECT Call.
This implementation of the PUT operation creates a copy of an object that is already stored in Amazon S3. A PUT copy operation is the same as performing a GET and then a PUT. Adding the request header, x-amz-copy-source, makes the PUT operation copy the source object into the destination bucket.
If the Put Object call has this header, then Put Object call will issue a rename.

Detect the presence of the extra header - x-amz-copy-source
Make sure that destination bucket exists.
