Downloading image with --progress fails for python3 with,
TypeError: 'IterableWithLength' object is not an iterator. This
is because IterableWithLength class does not implemented python3
compatible __next__ method.
Added __next__ method for python3 compatibility.

Closes-Bug: #1671365
This patch moves the glanceclient unit tests to the standard directory
(xxxclient/tests/unit) in preparation for adding functional gate tests
'check-glanceclient-dsvm-functional' in the same vein as existing client
tests for other projects, eg:
* check-novaclient-dsvm-functional
* check-keystoneclient-dsvm-functional
* check-neutronclient-dsvm-functional
