[ovs-dev] rhel: Install the network scripts in a new subpackage

Starting from Fedora 29, the legacy network scripts are installed in
the "network-scripts" package and so the network scripts ("ifup-ovs",
"ifdown-ovs") should be installed only when the "network-scripts" package
is installed.

This commit introduces (on Fedora 29+) a new subpackage
(network-scripts-openvswitch). This subpackage is installed, by default, only
if the "network-scripts" package is installed too (reverse weak dependency).

The package's name is following a new format that other projects are
using too.

The dnf installs weak dependencies unless told otherwise.

It requires the network-scripts if installed.

Conditionals look okay.

Looks correct if I read the guidelines correctly:
https://fedoraproject.org/wiki/Packaging:Guidelines 

It build the rpms correctly over here.

Thanks Timothy and Lubomir.

Actually, we also have dependencies in the systemd service
to the network service:

[Unit]                                                                                              
Description=Open vSwitch Forwarding Unit
After=ovsdb-server.service network-pre.target systemd-udev-settle.service
Before=network.target network.service
                      ^^^^^^^^^^^^^^^ 

Looks like that would be gone, right?

I checked and "network.service" is an auto-generated service
(systemd-sysv-generator - Unit generator for SysV init scripts)
from /etc/rc.d/init.d/network that brings Up and Down the interfaces
(if you don't use Network Manager).

The explicit dependency is needed in order to avoid having it to run
before openvswitch / ovsdb-server.
Moreover it's also harmless to have it when network.service doesn't
exists since, in this case, systemd will only ignore the dependency.

For example, NetworkManager.service has "Before=network.target
network.service" on Fedora Rawhide too, since Fedora Rawhide still have
the support for the legacy network scripts (/etc/rc.d/init.d/network, in
network-scripts package).

Alright, thanks for looking into this.

Thanks Timothy (and Flavio).  Applied to master.  Let me know if you
want it in branch-2.10 (or earlier?).
