Remove Glance v1 APIs tests code

Glance v1 APIs were removed in Rocky and tempest master
does not support the Rocky release. If glance v1 APIs
needs to be tested for older release then older Tempest
can be used.

Tempest is removing the Glance v1 APIs tests, config option,
and its service clients and this change is needed for that.
