feat(person-on-events): add option to delay all events (#13505)
* feat(person-on-events): add option to delay all events

This change implements the option outlined in
https://github.com/PostHog/product-internal/pull/405

Here I do not try to do any large structural changes to the code, I'll
leave that for later although it does mean the code has a few loose
couplings between pipeline steps that probably should be strongly
coupled. I've tried to comment these to try to make it clear about the
couplings.

I've also added a workflow to run the functional tests against both
configurations, which we can remove once we're happy with the new
implementation.

Things of note:

 1. We can't enable this for all users yet, not without the live events
    view and not without verifying that the buffer size is sufficiently
    large. We can however enable this for the test team and verify that
    it functions as expected.
 2. I have not handled the case mentioned in the above PR regarding
    guarding against processing the delayed events before all events in
    the delay window have been processed.

test(person-on-events): add currently failing test for person on events

This test doesn't work with the previous behaviour of the
person-on-events implementation, but should pass with the new delay all
events behaviour.

* add test for KafkaJSError behaviour

* add comment re delay

* add test for create_alias

* chore: increase exports timeout

It seems to fail in CI, but only for the delayed events enabled tests.
I'm not sure why, but I'm guessing it's because the events are further
delayed by the new implementation.

* chore: fix test

* add test for ordering of person properties

* use ubuntu-latest-8-cores runner

* add tests for plugin processEvent

* chore: ensure plugin processEvent isn't run multiple times

* expand on person properties ordering test

* wip

* wip

* add additional test

* change fullyProcessEvent to onlyUpdatePersonIdAssociations

* update test

* add test to ensure person properties do not propagate backwards in time

* simplicfy person property tests

* weaken guarantee in test

* chore: make sure we don't update properties on the first parse

We should only be updating person_id and asociated distinct_ids on first
parse.

* add tests for dropping events

* increase export timeout

* increase historical exports timeout

* increase default waitForExpect interval to 1 second
