Because the chains added by the network driver nftables backend will
go into a table used only by libvirt, we don't need to have "libvirt"
in the chain names. Instead, we can make them more descriptive and
less abrasive (by using lower case, and using full words rather than
abbreviations).
Also (again because nobody else is using the private "libvirt_network"
table) we can directly put our rules into the input ("guest_to_host"),
output ("host_to_guest"), and postrouting ("guest_nat") chains rather
than creating a subordinate chain as done in the iptables backend.
