Cherry Pick the update from the master branch to stable/colorado branch

These patches should be cherry picked to colorado branch:
https://gerrit.opnfv.org/gerrit/#/c/20077/
https://gerrit.opnfv.org/gerrit/#/c/20635/
https://gerrit.opnfv.org/gerrit/#/c/19833/
https://gerrit.opnfv.org/gerrit/#/c/19587/

But because the structure of the folder was changed in
https://gerrit.opnfv.org/gerrit/#/c/19833/
cherry pick using gerrit will lead to merge conflict,
has to update the colorado branch through this patch.

+Quota management for OpenStack multi-region deployments
+-------------------------------------------------------
+Kingbird is centralized synchronization service for multi-region OpenStack
+deployments. In OPNFV Colorado release, Kingbird provides centralized quota
+management feature. Administrator can set quota per project based in Kingbird
+and sync the quota limit to multi-region OpenStack periodiclly or on-demand.
+The tenant can check the total quota limit and usage from Kingbird for all
+regions. Administrator can aslo manage the default quota by quota class
+setting.
+
+Following quota items are supported to be managed in Kingbird:
+
+- **instances**: Number of instances allowed per project.
+- **cores**: Number of instance cores allowed per project.
+- **ram**: Megabytes of instance RAM allowed per project.
+- **metadata_items**: Number of metadata items allowed per instance.
+- **key_pairs**: Number of key pairs per user.
+- **fixed_ips**: Number of fixed IPs allowed per project,
+  valid if Nova Network is used.
+- **security_groups**: Number of security groups per project,
+  valid if Nova Network is used.
+- **floating_ips**: Number of floating IPs allowed per project,
+  valid if Nova Network is used.
+- **network**: Number of networks allowed per project,
+  valid if Neutron is used.
+- **subnet**: Number of subnets allowed per project,
+  valid if Neutron is used.
+- **port**: Number of ports allowed per project,
+  valid if Neutron is used.
+- **security_group**: Number of security groups allowed per project,
+  valid if Neutron is used.
+- **security_group_rule**: Number of security group rules allowed per project,
+  valid if Neutron is used.
+- **router**: Number of routers allowed per project,
+  valid if Neutron is used.
+- **floatingip**: Number of floating IPs allowed per project,
+  valid if Neutron is used.
+- **volumes**: Number of volumes allowed per project.
+- **snapshots**: Number of snapshots allowed per project.
+- **gigabytes**: Total amount of storage, in gigabytes, allowed for volumes
+  and snapshots per project.
+- **backups**: Number of volume backups allowed per project.
+- **backup_gigabytes**: Total amount of storage, in gigabytes, allowed for volume
+  backups per project.
+
+Only restful APIs are provided for Kingbird in Colorado release, so curl or
+other http client can be used to call Kingbird API.
+
+Before use the following command, get token, project id, and kingbird service
+endpoint first. Use $kb_token to repesent the token, and $admin_tenant_id as
+administrator project_id, and $tenant_id as the target project_id for quota
+management and $kb_ip_addr for the kingbird service endpoint ip address.
+
+Note:
+To view all tenants (projects), run:
+
+.. code-block:: bash
+
+    openstack project list
+
+To get token, run:
+
+.. code-block:: bash
+
+    openstack token issue
+
+To get Kingbird service endpoint, run:
+
+.. code-block:: bash
+
+    openstack endpoint list
