This PR implements a set of common TCP metrics exposed by OPNsense

Example: 

# HELP opnsense_proto_statistics_arp_received_requests_total Number of received ARP requests
# TYPE opnsense_proto_statistics_arp_received_requests_total counter
opnsense_proto_statistics_arp_received_requests_total{opnsense_instance="opnsense-local1"} 6.526501e+06
# HELP opnsense_proto_statistics_arp_sent_requests_total Number of sent ARP requests
# TYPE opnsense_proto_statistics_arp_sent_requests_total counter
opnsense_proto_statistics_arp_sent_requests_total{opnsense_instance="opnsense-local1"} 11673
# HELP opnsense_proto_statistics_tcp_connection_count_by_state Number of TCP connections by state
# TYPE opnsense_proto_statistics_tcp_connection_count_by_state gauge
