Description

When doing a copy, S3A always uses encryption configuration of the filesystem, rather than the source object. This behaviour may not have been intended, as in `RequestFactoryImpl.copyEncryptionParameters()`  it does copy source object encryption properties here , but a missing return statement means it ends up using the FS settings anyway. 

 

Proposed:

• If the copy is called by rename, always preserve source object encryption properties. 
• For all other copies, use current FS encryption settings.
