Ability to apply netem subcommands between a set of containers

[art-cmyk]

Currently it is possible to apply netem subcommands to egress traffic from a set or subset of containers. In my test scenario, I need to delay/corrupt/loss traffic/packets egressing from one container destined to a certain other container(s) on the network.

For example, I have peer1, pee2, peer3, api1, api2, db and rest containers. All peers can talk to each other and the apis. One of my tests is to delay/corrupt/loss some/all traffic between peer1 and peer3 or between peer2 and api1.

I don't think this is possible with pumba as of now. I stand corrected if it is and examples of how to achieve this would be greatly appreciated.

Could you add this functionality to pumba?

@ravitej-aluru thank you for the use case. I will think about the implementation. If you have any idea how to do it properly PR is welcomed.
