Public bug reported:

config generation with format yaml/json is broken with python3

Reproduction steps:-
git clone https://github.com/openstack/keystone
cd keystone
sed -i '/\[testenv\:genconfig\]/a basepython=python3' tox.ini
tox -egenconfig
.tox/genconfig/bin/oslo-config-generator --config-file=config-generator/keystone.conf --format yaml --output-file=keystone-schema.yaml

The above command works fine when basepython=python2

with "ini" it works fine:-
.tox/genconfig/bin/oslo-config-generator --config-file=config-generator/keystone.conf --format ini --output-file=keystone-schema.yaml


Actual Output:-
Traceback (most recent call last):
  File ".tox/genconfig/bin/oslo-config-generator", line 11, in <module>
    sys.exit(main())
  File "/home/ykarel/work/keystone/.tox/genconfig/lib/python3.6/site-packages/oslo_config/generator.py", line 770, in main
    generate(conf)
  File "/home/ykarel/work/keystone/.tox/genconfig/lib/python3.6/site-packages/oslo_config/generator.py", line 754, in generate
    conf=conf)
  File "/home/ykarel/work/keystone/.tox/genconfig/lib/python3.6/site-packages/oslo_config/generator.py", line 690, in _output_machine_readable
    output_data = _generate_machine_readable_data(groups, conf)
  File "/home/ykarel/work/keystone/.tox/genconfig/lib/python3.6/site-packages/oslo_config/generator.py", line 655, in _generate_machine_readable_data
    entry = _build_entry(opt, group_name, namespace[0], conf)
  File "/home/ykarel/work/keystone/.tox/genconfig/lib/python3.6/site-packages/oslo_config/generator.py", line 601, in _build_entry
    entry['type'] = _format_type_name(entry['type'])
  File "/home/ykarel/work/keystone/.tox/genconfig/lib/python3.6/site-packages/oslo_config/generator.py", line 157, in _format_type_name
    return _TYPE_NAMES[opt_type]
TypeError: unhashable type: 'HostAddress'

Expected Output:-
keystone-schema.yaml should be generated


This should be a bug for oslo.config, but found in keystone so reporting against it as well.
