Matthew Kassawara 5ee72cfa36 [install] Fix various minor problems

Fix the following minor problems to reduce work after
stable/liberty branching:

1) RDO: Revert Python MySQL library from PyMySQL to MySQL-python
   due to lack of support for the former.
2) RDO: Explicitly install 'ebtables' and 'ipset' packages due
   to dependency problems.
3) General: Change numbered list to bulleted list for lists with
   only one item.
4) General: Restructure horizon content to match other services.
   More duplication of content, but sometimes RST conditionals
   are terrible and distro packages should use the same
   configuration files.
5) General: Restructure NoSQL content to match SQL content.
6) General: Improve clarity of NTP content.

Orchestration

Create a template

The Orchestration service uses templates to describe stacks. To learn about the template language, see the Template Guide in the Heat developer documentation.

Create the demo-template.yml file with the following content:

heat_template_version: 2015-10-15
description: Launch a basic instance using the ``m1.tiny`` flavor and one network.

parameters:
  ImageID:
    type: string
    description: Image to use for the instance.
  NetID:
    type: string
    description: Network ID to use for the instance.

resources:
  server:
    type: OS::Nova::Server
    properties:
      image: { get_param: ImageID }
      flavor: m1.tiny
      networks:
      - network: { get_param: NetID }

outputs:
  instance_name:
    description: Name of the instance.
    value: { get_attr: [ server, name ] }
  instance_ip:
    description: IP address of the instance.
    value: { get_attr: [ server, first_address ] }

Create a stack

Create a stack using the demo-template.yml template.

Source the demo credentials to perform the following steps as a non-administrative project:
```
$ source demo-openrc.sh
```

Determine available networks.

$ neutron net-list
+--------------------------------------+---------+-----------------------------------------------------+
| id                                   | name    | subnets                                             |
+--------------------------------------+---------+-----------------------------------------------------+
| 9c13da20-4c4f-486f-a4e9-692e9ea397f1 | public  | 85140549-1f54-4bc6-a2c5-f08428de3f7a 203.0.113.0/24 |
| 303a9aaf-40fd-4fc8-9213-39bff933467b | private | ddeba0b1-21eb-471a-8f31-10f0e290cc36 172.16.1.0/24  |
+--------------------------------------+---------+-----------------------------------------------------+

Note

This output may differ from your environment.

Set the NET_ID environment variable to reflect the ID of a network. For example, using the public network:
```
$ export NET_ID=$(neutron net-list | awk '/ public / { print $2 }')
```

Create a stack of one CirrOS instance on the public network:

$ heat stack-create -f demo-template.yml -P "ImageID=cirros;NetID=$NET_ID" stack
+--------------------------------------+------------+--------------------+---------------------+--------------+
| id                                   | stack_name | stack_status       | creation_time       | updated_time |
+--------------------------------------+------------+--------------------+---------------------+--------------+
| dbf46d1b-0b97-4d45-a0b3-9662a1eb6cf3 | stack      | CREATE_IN_PROGRESS | 2015-10-13T15:27:20 | None         |
+--------------------------------------+------------+--------------------+---------------------+--------------+

After a short time, verify successful creation of the stack:

$ heat stack-list
+--------------------------------------+------------+-----------------+---------------------+--------------+
| id                                   | stack_name | stack_status    | creation_time       | updated_time |
+--------------------------------------+------------+-----------------+---------------------+--------------+
| dbf46d1b-0b97-4d45-a0b3-9662a1eb6cf3 | stack      | CREATE_COMPLETE | 2015-10-13T15:27:20 | None         |
+--------------------------------------+------------+-----------------+---------------------+--------------+

Show the name and IP address of the instance and compare with the output of the nova command:

$ heat output-show --all stack
[
  {
    "output_value": "stack-server-3nzfyfofu6d4",
    "description": "Name of the instance.",
    "output_key": "instance_name"
  },
  {
    "output_value": "10.4.31.106",
    "description": "IP address of the instance.",
    "output_key": "instance_ip"
  }
]

$ nova list
+--------------------------------------+---------------------------+--------+------------+-------------+---------------------------------+
| ID                                   | Name                      | Status | Task State | Power State | Networks                        |
+--------------------------------------+---------------------------+--------+------------+-------------+---------------------------------+
| 0fc2af0c-ae79-4d22-8f36-9e860c257da5 | stack-server-3nzfyfofu6d4 | ACTIVE | -          | Running     | public=10.4.31.106              |
+--------------------------------------+---------------------------+--------+------------+-------------+---------------------------------+

Delete the stack.
```
$ heat stack-delete stack
```
