Add dev env

[RonanMorgan]

A beautiful dev env which launch a Reoling dev camera and test if an alert has been generated by the engine

PS : I felt in a git hell by trying to remove all .env file in the history so I had to create a new PR

TODO :
=> understand the use case of the media API in order to mimic it in the python test media.py
=> create a centralised server in order to accept the loki call (whitelist some ip in the server itself ? how can we know the ip adress of gitAction servers)

[RonanMorgan]

understand and fix this error :

• we don't see anymore the lines after the grep :
  docker-compose logs --tail=20 | grep -i -E "error|exception" | grep -v -i "hypercorn.error"
