This adds an initial install of ceilometer to the install guide. This has not been tested. Also adds stub sections for adding agents/setting up notification to things. Change-Id: Ieb154f1412f32279550b0a5a4a0cafc1547b8b61

<title>Installing the central Metering Service components</title>
|

<para>The Metering service consists of an API service, collector
|
|
and a range of disparate agents. This procedure details
|
|
installing the "central" components, prior to installing agents
|
|
elsewhere, such as on the compute node.</para>
