Keystone does not add a default domain id to keystone.conf which breaks v2 clients

[Liam Young]

The keystone charm should set default_domain_id in the keystone.conf to ensure compatability with clients that do not supply domain info.

From http://docs.openstack.org/liberty/config-reference/content/section_keystone.conf.html:

# This references the domain to use for all Identity API v2 requests (which are
# not aware of domains). A domain with this ID will be created for you by
# keystone-manage db_sync in migration 008. The domain referenced by this ID
# cannot be deleted on the v3 API, to prevent accidentally breaking the v2 API.
# There is nothing special about this domain, other than the fact that it must
# exist to order to maintain support for your v2 clients. (string value)
#default_domain_id = default

    Add default_domain_id for Keystone v3 deploys

    The default_domain_id is used to specify a domain when the client
    hasn't explicitly set one. It defaults to 'default' which is fine
    for liberty and previous because the id of the default domain is,
     oddly, 'default' rather than a uuid. On Mitaka and higher it is
    a uuid so when keystone assumes the default domains id is 'default'
    it fails.

keystone-manage db_sync still not creating a domain by name "default". Is there a solution for that?
