Restructured and updated Neutron compute section
As part of the installation guide improvement project, I performed the following operations on the Neutron compute section: 1) Removed modularity since we will only support the ML2 plug-in for Icehouse. 2) Added some <procedure> tags to separate content. Future patches will add descriptions of each procedure. 3) Unified indentation and spacing. 4) Removed database configuration steps since Icehouse uses AMQP on compute nodes. 5) Removed *.ini configuration steps since Icehouse doesn't require editing *.ini files. 6) Moved 'auth_uri' key under [keystone_authtoken] section in neutron.conf. 7) Removed defunct 'auth_url' key. This section should continue to work for installations using the Open vSwitch plug-in for Neutron. Future patches will update the content to use ML2. Change-Id: I2c6207b26a8f85078ac680110d3d3244e8affd75 Partial-Bug: #1291071 Implements: blueprint networking-install-guide-improvements
