Add missing Keystone options to registration of config

This patchset adds missing Keystone options to registration
of config, including timeout, which is causing the following
error in testing:

packages/oslo_config/cfg.py", line 3130, in _get_opt_info
2018-06-12 20:28:40.318 9 ERROR armada.api     raise NoSuchOptError(opt_name, group)
2018-06-12 20:28:40.318 9 ERROR armada.api oslo_config.cfg.NoSuchOptError: no such option timeout in group [keystone_authtoken]
2018-06-12 20:28:40.318 9 ERROR armada.api

This fix is similar to a recent Shipyard patchset [0] which
aimed to solve the same issue but expands on it by following
Nova patterns here: [1].

This also updates the sample config file which now includes
the timeout option.
