What network conditions to test

[victorb]

I'm no ace in networking, so would be good to brainstorm about what kind of network conditions we want to test, so we can make sure we can simulate them within kubernetes.

Things like:

• nodes holding content dropping from the network, only leaving one node with the content, while many nodes requesting it
• shaky connections that are dropping and/or corrupting packets
• reordering packets?
• connections that are just slow and/or have a high latency
• nodes behind NAT and other stupid things

I've seen http://facebook.github.io/augmented-traffic-control/ before, not sure if we can use it or not. It's using iptables and tc so shouldn't be any problems.
