Pin glance-tempest-plugin for yoga/xena jobs

To have compatible glance-tempest-plugin version for
stable/xena & stable/yoga testing, we need to pin
it with 0.3.0.

Since glance-tempest-plugin have only rbac tests and as
per SRbac support in glance branch wise, pinned the plugin
with the specific tag for stable branches by keeping job name
same with different branches which are mutually exclusive.
