Expectation :

----------------------

ozone getKey should work even when only file-path is provided (without 
filename). It should create a file in the given file-path with its key's name 
as its name.

i.e,

given , /test1 is a directory .

if  ./ozone oz -getKey /nnvolume1/bucket123/passwd -file /test1  is run,

file 'passwd' should be created in the directory /test1 .
