feat: ser2sock: use a headless service

Since these generally talk to individual instances of physical hardware, it is unlikely that a user intends load balancing of multiple instances to multiple devices. Using a headless service (`clusterIP: None`) removes the k8s load balancer and allows clients to talk directly to the ser2sock pod via the service name.
