In nmcli we have renamed dhcp-send-hostname and dhcp-send-hostname-v2 to
dhcp-send-hostname-deprecated and dhcp-send-hostname so users don't need
to worry about the details of the weird workarounds that we sometimes
need to do to expand and/or deprecate some properties.
However, the autogenerated documentation didn't include this names. Add
---nmcli--- specific documentation, adding a new property-infos field
called "rename" with the new name used in nmcli. This field can be used
for more properties if we use the same strategy in the future.
