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

This section describes how to install and configure the Image service, code-named glance, on the controller node. For simplicity, this configuration stores images on the local file system.

Prerequisites

Before you install and configure the Image service, you must create a database, service credentials, and API endpoints.

To create the database, complete these steps:

Use the database access client to connect to the database server as the root user:

$ mysql -u root -p

Create the glance database:
MariaDB [(none)]> CREATE DATABASE glance;
Grant proper access to the glance database:
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
  IDENTIFIED BY 'GLANCE_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
  IDENTIFIED BY 'GLANCE_DBPASS';
Replace GLANCE_DBPASS with a suitable password.
Exit the database access client.

Source the admin credentials to gain access to admin-only CLI commands:
```
$ . admin-openrc
```

To create the service credentials, complete these steps:

Create the glance user:

$ openstack user create --domain default --password-prompt glance

User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | 3f4e777c4062483ab8d9edd7dff829df |
| name                | glance                           |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

Add the admin role to the glance user and service project:
```
$ openstack role add --project service --user glance admin
```
Note

This command provides no output.

Create the glance service entity:

$ openstack service create --name glance \
  --description "OpenStack Image" image

| Field       | Value                            |

| type        | image                            |

$ openstack endpoint create --region RegionOne \
  image public http://controller:9292
