Now when generating the config samples of Glance, glance-api.conf,
glance-glare.conf and glance-registry.conf will include duplicated
config options for osprofiler. It's because we're collecting
osprofiler's options at two places: etc/oslo-config-generator and
glance/opts.py. So to remove the duplication and keep consistenty
with the other options format, the patch removes the collecting
from etc/oslo-config-generator.
