Update the multisite documentations to reflect the progress in D
As some changes in OpenStack projects like KeyStone PKI token deprecation, L2GW moved away from Neutron stadium, Tricircle shrinked scope and became OpenStack big-tent project, and Kingbird has made great progress in feature development after the initial requirements discussion. Documents need to update to reflect these recent changes. python-kingbirdclient was introduced recently, so the usage guide is updated to use python-kingbirdclient. The new feature key pair synchronization is also included in the usage guide. Change-Id: Iad9fbd441d191defa5e8793633a626ab5a24f217 Signed-off-by: joehuang <joehuang@huawei.com>

-Multisite configuration guide

-
-Multisite identity service management
-=====================================
-
-Goal
-----
-
-A user should, using a single authentication point be able to manage virtual
-resources spread over multiple OpenStack regions.
-
-Before you read
----------------
-
-This chapter does not intend to cover all configuration of KeyStone and other
-OpenStack services to work together with KeyStone.
-
-This chapter focuses only on the configuration part should be taken into
-account in multi-site scenario.
-
-Please read the configuration documentation related to identity management
-of OpenStack for all configuration items.
-
-http://docs.openstack.org/liberty/config-reference/content/ch_configuring-openstack-identity.html
-
-How to configure the database cluster for synchronization or asynchrounous
-repliation in multi-site scenario is out of scope of this document. The only
-remainder is that for the synchronization or replication, only Keystone
-database is required. If you are using MySQL, you can configure like this:
-
-In the master:
-
- .. code-block:: bash
-
- binlog-do-db=keystone
-
-In the slave:
-
- .. code-block:: bash
-
- replicate-do-db=keystone
-
-
-Deployment options
-------------------
-
-For each detail description of each deployment option, please refer to the
-admin-user-guide.
-
-- Distributed KeyStone service with PKI token
-
- In KeyStone configuration file, PKI token format should be configured
-
- .. code-block:: bash
-
- provider = pki
-
- or
-
- .. code-block:: bash
-
- provider = pkiz
-
- In the [keystone_authtoken] section of each OpenStack service configuration
- file in each site, configure the identity_url and auth_uri to the address
- of KeyStone service
-
- .. code-block:: bash
-
- identity_uri = https://keystone.your.com:35357/
- auth_uri = http://keystone.your.com:5000/v2.0
-
- It's better to use domain name for the KeyStone service, but not to use IP
- address directly, especially if you deployed KeyStone service in at least
- two sites for site level high availability.
-
-- Distributed KeyStone service with Fernet token
-- Distributed KeyStone service with Fernet token + Async replication (
- star-mode).
-
- In these two deployment options, the token validation is planned to be done
- in local site.
-
- In KeyStone configuration file, Fernet token format should be configured
-
- .. code-block:: bash
-
- provider = fernet
-
- In the [keystone_authtoken] section of each OpenStack service configuration
- file in each site, configure the identity_url and auth_uri to the address
- of local KeyStone service
-
- .. code-block:: bash
-
- identity_uri = https://local-keystone.your.com:35357/
- auth_uri = http://local-keystone.your.com:5000/v2.0
-
- and especially, configure the region_name to your local region name, for
- example, if you are configuring services in RegionOne, and there is local
- KeyStone service in RegionOne, then
-
- .. code-block:: bash
-
- region_name = RegionOne
