Packet capture context

[oshaked1]

1. Explain what the PR does

This PR adds context information to pcap files generated by Tracee. Based on the type of pcap, an interface description that contains various pieces of context information in JSON format is added.

Example of an interface description for a process pcap:

{"container":{"id":"c373adfdc4ac4c3a330c4fda09ad9398bcfb99c381b97cb044c813a397547def","name":"gallant_nightingale","image":"busybox:latest","imageDigest":"busybox@sha256:5eef5ed34e1e1ff0a4ae850395cbf665c4de6b4b83a32a0bc7bcb998e24e7bbb"},"kubernetes":{"podName":"","podNamespace":"","podUID":"","podSandbox":false},"hostName":"c373adfdc4ac","processName":"ping","process":{"threadStartTime":1716378637481073915,"processId":1,"cgroupId":526,"threadId":1,"parentProcessId":0,"hostProcessId":191684,"hostThreadId":191684,"hostParentProcessId":191665,"userId":0,"mountNamespace":4026532371,"pidNamespace":4026532374,"executable":""}}

This closes #4050.

2. Explain how to test it

An integration test was added for the context information.

To manually read the interface description containing the context information, use the following python script with the pcap file as an argument:

import sys
import pcapng

pcap_path = sys.argv[1]
with open(pcap_path, 'rb') as f:
    scanner = pcapng.FileScanner(f)
    for block in scanner:
        if isinstance(block, pcapng.blocks.InterfaceDescription):
            print(block.options['if_description'])
