Hugo Geoffroy c784d3ab76 nixos/haproxy: add reloading support, use upstream service hardening
Refactor the systemd service definition for the haproxy reverse proxy,
using the upstream systemd service definition. This allows the service
to be reloaded on changes, preserving existing server state, and adds
some hardening options.
