TestOzoneFileSystem testTrash fails while setting enableFsPaths to true. This is because of using DeleteKeyRequest for delete.
There are 2 operations that happen when a key is moved to Trash 1. rename 2 .delete .
While Renaming a directory key, the renamedKey is stored in KeyTable with "/" (RenameKeyRequest) irrespective of enableFsPaths value but while deleting a key via DeleteKeyRequest the "/" is removed and a lookup is done on KeyTable which results in KEY_NOT_FOUND. Using DeleteKeys instead of DeleteKey will solve this issue as a lookup is not done on the normalised key.
This PR explains why normalisation is not done while rename
