Moving cinderclient to test-requirements.txt made glance gate logs very noisy

[Louis Taylor]

After https://review.openstack.org/#/c/197766/ was merged, glance is temporarily gating against glance_store master. When https://review.openstack.org/#/c/189237/ was merged, the glance gate started spewing errors, since glance_store's test-requirements.txt isn't sourced to make python-cinderclient unavailable.

From gate-glance-python27 logs:

This didn't actually break the gate. Phew!
