C202301 - API finalization

[infotel4iarc]

Improve the CSV bulk import by having an asynchronous process to avoid a too long http request (risk of timeout):

• create a worker
• return the id of the worker
• add entry point to get the status of the worker
• add entry point to get the final report when the worker has finished

The branche is: https://github.com/infotel4iarc/CanReg5-RestAPI/tree/C202301_API_finalization

The follwing points were done:

• As said in the issue, a worker was created to manage the uploaded csv, the worker's id will be returned once csv uploaded
• Every 5 min, a task will be executed to check the oldest worker waiting (the oldest csv uploded but not yet imported). The csv will be imported and a report will be generated (can be checked with the endpoint mentioned in the next point)
• Created entry points to get the status and the report of the worker
• Added property to define report file's directory
