TOP-847: Implement functional test single scan
This updates the existing integration test to revert back to the ITF integration test defined here: https://skaoffice.jamacloud.com/perspective.req#/testCases/1108096?projectId=335
Specifically, it goes back to a single observation where the input is simulated from a PCAP file, not the CNIC-VD.
