tempest.conf.sample generator causes the dup entities in same group

[Zhikun Liu]

Duplicate entities means that they have same 'name', 'default value' and 'help message'.

Current generator can not deal with the duplicate entities in different groups. They will be added into the same group in tempest.conf.sample. As generator compares opt with the opts in groups to find the group in which the opt is, duplicate opts will be matched in the same group.

For example:
[network-feature-enabled] has 3 api_extensions in tempest.conf.sample. 2 of them should belong to [compute_features_group] and [volume_feature_group]. I reported a bug https://bugs.launchpad.net/tempest/+bug/1280085, and submit a patch making the dup entities different to fix it. But that's not the root cause.

This isn't a tempest bug, the sample generator is synced from oslo-incubator. This needs to be fixed in oslo then we can just update the copy in the tempest repo.

[Doug Hellmann (doug-hellmann)]

The simplest fix for this is likely to be to update tempest to use the new config generator in oslo.config instead of the one in the incubator. http://docs.openstack.org/developer/oslo.config/generator.html

Thanks Doug. Indeed it looks like the new generator doesn't have this issue; added entry_points to tempest and then tested with some identical opts. Was able to see the bug behavior with the old generator and see desired behavior with the new generator.

Will polish this up for submission.
