Review Comment:
   @dombizita For OMKeyRenamRequest, we should not allow empty key name, that 
part is ok. Only for OMKeyRenameRequestWithFSO, can remove toKeyName.length() 
== 0 check, and any further check if causing issue.
   I am proposing to fix at OM layer, because other client integration do not 
need any change when passing source and destination, and OM layer should 
support api with this behavior.
