Push errors to Bugsnag asynchronously

[lobodol]

Description

While taking a look at my Datadog's longest traces, I noticed that, for a 404, 80% of the time is spent in curl sending data to Bugsnag:

Describe the solution you'd like
My proposal is to add the possibility to push data to Bugsnag asynchronously, relying on Symfony Messenger.

Hi @lobodol

We have added a task to our backlog to allow users to override the Symfony delivery system, which would give you the ability to report errors to BugSnag asynchronously. We can't currently give an ETA on when this could be looked at, but we will make sure to update this thread with any future developments around this.

It is worth noting that we do delivery in the kernel.terminate event, so the request happens after the response has been sent to the user. This means that, although you may notice 80% of the time in your 404s is spent sending data to BugSnag, this will not be affecting the user experience.
