[pve-devel] [PATCH manager] improve gui cidr matching

[Dominik Csapak]

with this fix, we (again) allow ipv4 cidr to be as low as 8
also check the cidr for ipv6 and show the valid ranges in the
error text

sorry for the additional translation string, but in
my opinion, we should tell the user which ranges are valid

if someone has a better idea how we can display that, please
tell me :)
