Benchmark

For our benchmark, we used a use case Salt Typhhon like meaning 18 injects having 1000 endpoints throwing each 4 execution trace. All these injects have an output parser. Do note that the endpoints for our tests are fake endpoints. They are just threads on my machine doing post requests with their execution trace.
In total, we are supposed to have 72 000 execution traces ingested.

Current perfs with existing method :
Only 870 traces are pushed in 10mins. The backend can't follow to deal with more and the app is unusable during the benchmark. On average, each trace is taking around 20s to be ingested so around 3 trace ingested by minutes.

Perfs with this PR :
Since we're now using RabbitMQ, we can see the graph of ingestion in it :

We can see that all the 72 000 traces are pushed in a minute. They are then ingested in around 6 minutes. The ingestion varies quite a lot but it's around 200 ingestion per second or 12 000 per minute.

Some problems during my tests:

• Can't relaunch an existing atomic testing after the migration

- Error in logs during execution of an atomic testing: - Final inject status stays in pending:
