stl: pass client object to loaded python profiles

[rjarry]

Pass an extra "client" argument to the get_streams() method of python traffic profiles. This allows profiles to dynamically resolve destination mac addresses using the ARP and IPv6ND services.

Add an example l3.py profile that supports both IPv4 and IPv6 left/right addresses and gateways.

Example IPv4:

$ ./ndr --stl --ports 0 1 --force-map --bi-dir --opt-bin-search \
   --profile stl/l3.py --prof-tun \
   left-ip=172.16.0.1,left-gw=172.16.0.254,right-ip=172.16.1.1,right-gw=172.16.1.254

ARP: ---> who has '172.16.0.254' ? tell '172.16.0.1'
ARP: <--- '172.16.0.254 is at '30:3e:a7:0b:ea:78'
ARP: ---> who has '172.16.1.254' ? tell '172.16.1.1'
ARP: <--- '172.16.1.254 is at '30:3e:a7:0b:ea:79'
