Matt Kassawara f3ecb24050 Restructured and updated Nova networking sections
As part of the installation guide improvement project, I performed
the following operations on the Nova networking sections of the
installation guide:

1) Split configuration and initial network creation section to align
   with structure of Neutron chapter.
2) Aligned phrasing/wording and examples with Neutron chapter.
3) Removed defunct ch_neutron.xml from repository.
4) Modified links affected by these changes.
5) Updated glossary as necessary.

<title>Configure compute node</title>
<para>Legacy networking only involves compute nodes. This section covers
deployment of a simple <glossterm>flat network</glossterm> that provides
IP addresses to your instances via <glossterm>DHCP</glossterm>. If your
environment includes multiple compute nodes, the
<glossterm>multi-host</glossterm> feature provides redundancy by spreading
network functions across compute nodes.</para>
