Support faulty/slow/interrupted pod networking

[mffiedler]

One class of network chaos to support is for pod networking (vs host/node networking). Scenarios might be:

• high latency networking environments
  -networks that are expected to periodically disconnect (moving vehicles)
• poor quality networks (packet corruption, high tx retries, etc)

One possible way for Kraken to support these scenarios is via integration of Litmus experiments:
Pod network latency
Pod network loss
Pod network corruption

This issue might need to be broken out into multiple issues.

This is now supported in Krkn thanks to @yogananth-subramanian at both pod and node level: https://github.com/redhat-chaos/krkn/blob/main/docs/pod_network_scenarios.md and https://github.com/redhat-chaos/krkn/blob/main/docs/network_chaos.md. Thanks.
