Open vSwitch recently added support for recording and replaying streams and
some other types of events:
  https://docs.openvswitch.org/en/latest/topics/record-replay/

Since OVN is based on OVS libraries, it may use this functionality almost
for free, we only need to add support for cmdline arguments to OVN daemons
(northd, ovn-controller, ovn-nbctl in daemon mode).

This task is to add this support and also record all the processes while
running unit and system tests, so it will be possible to easily reproduce
issues caught by CI systems (e.g., GitHub Actions) or during manual testing.
