In the tests which are using tcpdump to check if traffic is going through the right node(s) there was only check if something was captured or not. But in case of failure we didn't know what was captured what caused issue. Now this patch adds logging of the packets captured on all of the nodes in case if the assertion in test failed. Hopefully that will help debugging issues like in the related bug. Related-bug: #OSPRH-11312 Change-Id: I1025ae0c9dbb50d187b2827a8a7c4de864e35875
