reduce conntrack UDP timeouts
...
This only applies to outbound NTP requests since we use notrack for our
UDP services and DNS-over-TLS for our local resolver. We'd have no need
for longer timeouts even if that wasn't the case.

add nmap package across servers mainly for nping
...
It's extremely useful to have this around for debugging network issues,
testing firewall rules and other purposes. It's not particularly useful
having nmap itself, but nping and to a lesser extent ncat are great to
have available.

nftables: drop instead of reject for unused ports
...
This provides consistency with DDoS protection services placed in front
of the services rather than the behavior changing based on whether DDoS
protection is active. This doesn't help with protecting against attacks
since they'll almost always be targeting ports with services active or
exhausting inbound bandwidth via UDP reflection attacks. This appears to
be the standard approach used by most large tech companies.
