cloud: clean up networking configuration

Browse Source 
We're no longer using legacy network scripts to bring up networking.
We're using NetworkManager and now in F33+ networkmanager will even
default to writing out new configuration as NM keyfiles in
/etc/NetworkManager/system-connections/. We don't need to lay down
a networking config for eth0. Either cloud-init will do that for us
or NetworkManager will default to DHCP anyway.

We also don't need to populate /etc/hosts as that will get done on
boot too with the same content we were writing there already.
