move existing content into the new standard structure

This patch rearranges and reformats existing content.

It replaces the home-grown autodoc feature with the one built into pbr,
for consistency with other OpenStack projects.

It depends on the doc-migration spec and a pbr feature to allow us to
specify where the autodoc content should go in the source tree during
the build.

+=============================
+ Command-line Tool Reference
+=============================
+
+In order to use the CLI, you must provide your OpenStack username,
+password, tenant, and auth endpoint. Use the corresponding
+configuration options (``--os-username``, ``--os-password``,
+``--os-tenant-id``, and ``--os-auth-url``) or set them in environment
+variables::
+
+    export OS_USERNAME=user
+    export OS_PASSWORD=pass
+    export OS_TENANT_ID=b363706f891f48019483f8bd6503c54b
+    export OS_AUTH_URL=http://auth.example.com:5000/v2.0
+
+The command line tool will attempt to reauthenticate using your
+provided credentials for every request. You can override this behavior
+by manually supplying an auth token using ``--os-image-url`` and
+``--os-auth-token``. You can alternatively set these environment
+variables::
+
+    export OS_IMAGE_URL=http://glance.example.org:9292/
+    export OS_AUTH_TOKEN=3bcc3d3a03f44e3d8377f9247b0ad155
+
+Once you've configured your authentication parameters, you can run
+``glance help`` to see a complete listing of available commands.
