Investigate a timeout when delivering webhook

[ksy36]

There is a timeout error in https://github.com/webcompat/web-bugs-private/issues/24214 when delivering a webhook with "action": "opened" :

We couldn’t deliver this payload: timed out

The comment with public issue url was added and a classification request was sent. I think the timeout is happening at classification result retrieval step.

When I redilivered the webhook, the classification was performed successfully and label was added

Two more issues that should have been labelled as invalid, but didn't

We discussed a bit with @ksy36 about the options.

Let's try to measure an optimal time for waiting before retrying to call HTTP service by adding a timer at the beginning of this function https://github.com/webcompat/webcompat.com/blob/master/webcompat/webhooks/ml.py#L29
