Matthew Kassawara 8ddea61d21 More updates for Juno
I updated the installation guide for Juno as follows:

1) Unifed RHEL/CentOS/Fedora steps to use systemd through
   networking chapter. Will work on other chapters in a
   future patch.
2) Split openSUSE steps to use systemd.
3) Removed database configuration from nova on compute
   nodes (yay!).
4) Added workaround for RDO changing the neutron default
   "auth_strategy=keystone" back to "auth_strategy=noauth".
5) Re-add workaround for broken RDO neutron init scripts. See
   bug #1375746 for more information.
6) Applied other changes for RHEL/CentOS 7.
7) Improved nova-network content.
8) Other minor fixes.
