network: adapt apply config section to PVE 7

Browse Source 
ifupdown2 is now installed by default, we can therefore omit the whole
installation part except a small note for people who installed PVE on
top of Debian.

also mention the CLI variant for users who like to edit the network
config directly or are using some config management tools

Reboot Node to apply
^^^^^^^^^^^^^^^^^^^^
With the default installed `ifupdown` network managing package you need to
reboot to commit any pending network changes. Most of the time, the basic {pve}
network setup is stable and does not change often, so rebooting should not be
required often.
One way to apply a new network configuration is to reboot the node.
Reload Network with ifupdown2
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
With the optional `ifupdown2` network managing package you also can reload the
network configuration live, without requiring a reboot.
With the 'ifupdown2' package (default since {pve} 7), it is possible to apply
network configuration changes without a reboot. If you change the network
configuration via the GUI, you can click the 'Apply Configuration' button. Run
the following command if you make changes directly to the
`/etc/network/interfaces` file:
Since {pve} 6.1 you can apply pending network changes over the web-interface,
using the 'Apply Configuration' button in the 'Network' panel of a node.

ifreload -a

To install 'ifupdown2' ensure you have the latest {pve} updates installed, then
WARNING: installing 'ifupdown2' will remove 'ifupdown', but as the removal
scripts of 'ifupdown' before version '0.8.35+pve1' have a issue where network
is fully stopped on removal footnote:[Introduced with Debian Buster:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=945877] you *must* ensure
that you have a up to date 'ifupdown' package version.
For the installation itself you can then simply do:
apt install ifupdown2
With that you're all set. You can also switch back to the 'ifupdown' variant at
any time, if you run into issues.
NOTE: If you installed {pve} on top of Debian, make sure 'ifupdown2' is
installed: 'apt install ifupdown2'
