Fix or remove noisy ddtrace info log for after_in_child hook

[robrap]

Here is an example message:

2025-01-06 16:06:52,552 INFO 1 [request_id None] [ddtrace.internal.forksafe] forksafe.py:69 - after_in_child hook reset_at_fork was unregistered without first being registered

On 2024-01-06, I added a temp log retention filter of 99% exclusion for:

• "after_in_child hook reset_at_fork was unregistered without first being registered"

Note: Although we aren't indexing this, it will still appear in Live Tail view.

Acceptance Criteria (Part 1):

• Create or update DD support ticket to learn if DD will fix or if this should be ignored.

Acceptance Criteria (Part 2 - Deferred):

• Confirm fix (log messages no longer appearing), or bump filter to 100% and remove "[TEMP]" designation from name if we need to permanently ignore.

Arch-BOM (Tim) will inform DataDog about this, and support Aurora (Rodrigo) while that team looks into it for their specific service.

@timmc-edx: I unassigned you because you are no longer on-call. Either I will get to this as part of on-call, or anyone who frees up can get this. Also, I updated the AC to clarify that the only think we are doing for not is creating the DD support ticket.

The support ticket was created: https://help.datadoghq.com/hc/en-us/requests/1995270. I'm going to move this to the backlog, although I may follow-up on the DD Support ticket.

I added some comments to the DD ticket. I also rehydrated logs so I could discover when this problem first started. The problem started for us around 12pm on Oct 30, 2024.
