Set hostname per MAC address

[emmaly]

Enable the ability to declare a static hostname attached to a MAC address. This way we don't have to do a static IP assignment simply because we want a static hostname assignment. It allows us to disregard the client-provided hostname when doing DNS registrations, or could allow us to regard both our statically assigned hostname along with the client-provided one.

So far all values are FQDN. Is there a reasonable way to allow this value to be non-FQDN (appending the DHCP domain) while also allowing FQDN (not appending, no matter where they're at)? Usually folks would put a dot at the end to indicate FQDN. We haven't been doing that. Maybe we assume no dots at all means non-FQDN and any dots at all means FQDN? That seems inconsistent with other systems. But for the moment, I'm going to go that route. When we make a decision here, we should adjust.

Is it possible that we're already covered by dhcp.go:317?
