Split glanceclient functional tests

Prepare for the Image API v1 to be removed from glance during Rocky
by splitting the functional tests that hit v1 from the tests that hit
v2.  Introduce a new job that runs the functional-v1 tests against a
devstack running glance stable/queens, and configure this job for both
check and gate for the glanceclient.  The v2 functional tests
continue to be run for both check and gate against a devstack running
glance master.
