Hello TIA

If you do not have a local/LAN DNS server neither a caching DNS configuration on your machine, I can't see a reason to add localhost to the list of your DNS servers...

The usual reason is that you want caching and you may have added a local zone for your own machines.

The idea behind DHCP is to distribute gateway, dns, ntp and other servers to the clients, beside the IP addresses. It's the way it works to have the /etc/resolv.conf overwritten on machine reboot and DHCP refresh.

DHCP will offer nameservers. You don't have to accept them. Somewhere in the network manager GUI there should be a checkbox to control this - although I think there have been bugs in various versions.
