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.

Enable Object Storage meters

Telemetry uses a combination of polling and notifications to collect Object Storage meters.

Note

Your environment must include the Object Storage service.

Prerequisites

The Telemetry service requires access to the Object Storage service using the ResellerAdmin role. Perform these steps on the controller node.

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

Create the ResellerAdmin role:

$ openstack role create ResellerAdmin
+-------+----------------------------------+
| Field | Value                            |
+-------+----------------------------------+
| id    | 462fa46c13fd4798a95a3bfbe27b5e54 |
| name  | ResellerAdmin                    |
+-------+----------------------------------+

Add the ResellerAdmin role to the ceilometer user:
```
$ openstack role add --project service --user ceilometer ResellerAdmin
```
Note

This command provides no output.

Install components

Install the packages:

ubuntu or debian

# apt-get install python-ceilometermiddleware

rdo

# yum install python-ceilometermiddleware

obs

# zypper install python-ceilometermiddleware

Configure Object Storage to use Telemetry

Perform these steps on the controller and any other nodes that run the Object Storage proxy service.

Edit the /etc/swift/proxy-server.conf file and complete the following actions:

In the [filter:keystoneauth] section, add the ResellerAdmin role:

[filter:keystoneauth]
...
operator_roles = admin, user, ResellerAdmin

In the [pipeline:main] section, add ceilometer:

[pipeline:main]
pipeline = catch_errors gatekeeper healthcheck proxy-logging cache
container_sync bulk ratelimit authtoken keystoneauth container-quotas
account-quotas slo dlo versioned_writes proxy-logging ceilometer
proxy-server

In the [filter:ceilometer] section, configure notifications:

[filter:ceilometer]
paste.filter_factory = ceilometermiddleware.swift:filter_factory
...
control_exchange = swift
url = rabbit://openstack:RABBIT_PASS@controller:5672/
driver = messagingv2
topic = notifications
log_level = WARN

Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.

Finalize installation

rdo or obs

Restart the Object Storage proxy service:

# systemctl restart openstack-swift-proxy.service

ubuntu

Restart the Object Storage proxy service:
```
# service swift-proxy restart
```
