[FEA] Support Control Protocols like Ping and Multicast

[awthomp]

Describe the solution you'd like
Integrate tools to manage, monitor, and coordinate network traffic between sensors and GPUs like ping and multicast

[cliffburdick]

For this one we may just want to rely on users to configure flow isolation. When that's enabled multicast and ping will go to the kernel, and we can use normal linux ways of working with it. We might want to not add this until that's not sufficient.
