Code Issues Proposed changes

Fix issues of multi-region devstack environment setup

Browse Source 
1. What is the problem
(1) Currently we only add bridge mapping for br-extern in RegionTwo by
default in plugin.sh, so if we only have one node for the tempest
test, we can not test the cases that network is created in physical
network of "extern".
(2) Keystone url is not configured explicitly in tricircle local
Neutron plugin configuration so local Neutron plugin may fail to connect
to central Neutron.
(3) In multi-pod installation, Nova services in node2 fail to talk to
placement API due to placement API configuration problem, which leads
to instance booting error.

2. What is the solution to the problem
(1) Add bridge mapping for br-extern both in RegionOne and RegionTwo
by default.
(2) Configure two options client.identity_url and client.auth_url in
plugin.sh to make sure local Neutron server can correctly connect to
central Neutron server.
(3) Update multi-pod installation guide to add a workaround for the
placement API problem.

3. What the features need to be implemented to the Tricircle
No new features.

@ -204,6 +204,19 @@ In pod2 in node2 for OpenStack RegionTwo,
- 6 After DevStack successfully starts, the setup is finished.
.. note:: In the newest version of codes, we may fail to boot an instance in
node2. The reason is that Apache configuration file of Nova placement API
doesn't grant access right to the placement API bin folder. You can use
"screen -r" to check placement API is working well or not. If placement API
is in stuck status, manually update "/etc/apache2/sites-enabled/placement-api.conf"
placement API configuration file in node2 to add the following section::
<Directory /usr/local/bin>
Require all granted
</Directory>
After update, restart Apache service first, and then placement API.
