For troubleshooting, provide a mechanism to trigger packet capture on demand (full packet content), targeting a specific pod or a set of pods (e.g. by controller name or by labels).

A new CRD must be created to describe the packet-capture setup. It should include:

• The target pod(s) identification (pod name, or controller name, or pod labels)
• Some optional filters:
  • Flow direction: ingress / egress / both
  • Peer name / type / ip / port
• Time limit and/or packet count limit (capture first N packets)
• Sampling

A kubectl / oc plugin should also be created to capture from the command line and get the output

Note, there can be a follow-up to add an UI
