Fixes #37450 - start free_ips service for native ms dhcp

Fixes #37413 - Let the kernel assign a TCP port in tests

This binds on port 0, which lets the kernel decide which port to use.
The port is then read back from the listener. Because the kernel knows
which ports it's allowed to bind to, it removes the risk of a failure...

Fixes #37355 - Explicitly query for IPv4 address in omapi code

The omapi API is IPv4-only so the DNS lookup should also only ask for
IPv4 addresses. Otherwise it may return an IPv6 address which ip2hex
can't deal with.

Fixes #37147 - Pass --fail option to curl

This prevents curl from writing out error pages, for example when the
URL returns a HTTP 404.

It still doesn't return any error to Foreman since the TFTP
/fetch_boot_file only starts a thread and there's no way to monitor it....
