In its recent history OVN had a few segfaults or asserts (e.g. https://issues.redhat.com/browse/FDP-2783 or https://issues.redhat.com/browse/FDP-2779 .

There were similar asserts in the past, due to the complexity of properly handle I-P, often when multiple commands (such as lsp-add and lsp-del of the same port) are handled at the same time.

A script calling ls-add, lsp-add, acl-add, acl-del, pg-add, pg-del, lb-add, lb-del ... "randomly" proved as sometimes catching those asserts.

Such scripts loops and randomly calls some of the commands in a loop and not others, so some loops will for instance only call ls-add, others will call ls-add, lsp-ad, ls-del ...

Hence running this script for e.g 10 seconds cover many test cases at once.

This task should also (try to) provide a way to reproduce the "random" run once an issue has been detected.
