Doug Hellmann c7bfdbb44f split install guide into separate files by OS

Provide a script for interpreting the "only" directives and splitting
the existing content up into standalone files for each OS to make it
easier for project teams to copy the parts they need into their own
project documentation trees without requiring separate platform builds.

The files have been hand-edited to pass the niceness check and to allow
the install guide to build.

The script for building the guide has been changed to not build separate
copies per OS.

Install and configure compute node

The compute node handles connectivity and security groups <security group> for instances.

Install the components

# apt install neutron-linuxbridge-agent

Configure the common component

The Networking common component configuration includes the authentication mechanism, message queue, and plug-in.

Edit the /etc/neutron/neutron.conf file and complete the following actions:
- In the [database] section, comment out any connection options because compute nodes do not directly access the database.
- In the [DEFAULT] section, configure RabbitMQ message queue access:
```
[DEFAULT]
# ...
transport_url = rabbit://openstack:RABBIT_PASS@controller
```
  Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.
- In the [DEFAULT] and [keystone_authtoken] sections, configure Identity service access:
```
[DEFAULT]
# ...
auth_strategy = keystone

[keystone_authtoken]
# ...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = NEUTRON_PASS
```
  Replace NEUTRON_PASS with the password you chose for the neutron user in the Identity service.
  
  Note
  
  Comment out or remove any other options in the [keystone_authtoken] section.

Configure networking options

Choose the same networking option that you chose for the controller node to configure services specific to it. Afterwards, return here and proceed to neutron-compute-compute-ubuntu.

neutron-compute-install-option1.rst neutron-compute-install-option2.rst

Configure the Compute service to use the Networking service

Edit the /etc/nova/nova.conf file and complete the following actions:

In the [neutron] section, configure access parameters:

[neutron]
# ...
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = NEUTRON_PASS

Replace NEUTRON_PASS with the password you chose for the neutron user in the Identity service.

Finalize installation

Restart the Compute service:
```
# service nova-compute restart
```

Restart the Linux bridge agent:

# service neutron-linuxbridge-agent restart
