feat(event): Add pay_in_advance flag in grouped charges view (getlago…

…#2300)

## Context

This PR update the `billable_metrics_grouped_charges` view introduced in
getlago#2231 to allow a better
filtering of events related to in advance charges.

Today all event having the code of a billable metric related to an in
advance charge is sent to the event_worker even if no subscription is
attached to it leading to a lot of load on the worker for jobs that will
in the end not be charged

## Description

This PR will allow us to the update the ingest service so that only
event related to an in advance charge on a active subscription are sent
to the event worker
