Move unit tests to standard directory

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
