Dependant on HDDS-522. This patch needs to be applied on top of HDDS-522
 # Done

 # When I use as you have suggested, it is not working. Not sure as my return is Response
we need explicit conversion.

Changed the signature to remove volume, and also updated the GetObject. After this change
when I am using cp command 

'aws s3 --endpoint-url [http://s3g:9878|http://s3g:9878/] cp /tmp/testfile [s3://bucket1/|s3://bucket1/dir1/dir2/file]testfile 

upload: ../../tmp/testfile to [s3://bucket1/testfile]

This working fine, but when I give path as below it is failing. Not sure of the problem here.

'aws s3 --endpoint-url [http://s3g:9878|http://s3g:9878/] cp /tmp/testfile s3://bucket1/dir1/dir2/file

this is failing with below error
|${output} = Completed 29 Bytes/29 Bytes with 1 file(s) remaining upload failed: ../../tmp/testfile
to [s3://bucket1/dir1/dir2/file] An error occurred (405) when calling the PutObject operation:
Method Not Allowed|

> 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. 
> Work Items or JIRAs
> Detect the presence of the extra header - x-amz-copy-source
> Make sure that destination bucket exists.
> The AWS reference is here:
> https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectCOPY.html
> (This jira is marked as newbie as it requires only basic Ozone knowledge. If somebody
would be interested, I can be more specific, explain what we need or help).
