add test for snmp

[sopos]

snmpd manually executed listens correctly while in this framework netstat does not report anything

# sed 's/^/    /' ./server 
#!/bin/bash -xe

cat > ./config << EOF
rocommunity public
EOF
ip a
/usr/sbin/snmpd -f -c ./config udp6:[::]:161 udp:0.0.0.0:161 tcp:0.0.0.0:161 tcp6:[::]:161 &
ps aux | grep snmp || :
sleep 2
ps uax | grep snmp || :
netstat -putna
wait $!
# sed 's/^/    /' ./client 
#!/bin/bash -e

exec /usr/bin/snmpgetnext -v 2c -c public $DESTINATION .
# sed 's/^/    /' ./deps 
net-snmp
net-snmp-utils

the client side is also killed just a while after snmpgetnext is started ~200ms

@sopos Sorry for late response.

Your netstat probably doesn't see inside the network namespaces. Debugging with network-testing must be done with care. I would like to improve that in the future. The client should be pretty quick to start. If your services work separately from network-testing, they are probably good for merging and we would fix network-testing afterwards.
