Create an ARA CLI for smoother Continuous Integration

**What it's the actual situation on ARA ?**
Logic and code to send results to ARA is maintained throughout every repository (in Decathlon)

**Describe the solution you'd like**
Some sorts of reusable code (we talked about Docker images) that own this logic and make it accessible to:
- simplify the setup for every users
- modify logic according to ARA evolutions with a reduced risk of breaking changes for users

**Describe alternatives you've considered**
An ARA cli? 💯

No files, tests, or entry points are identified in the issue; start by examining the ARA repository's existing result-sending logic and CI integration points. Done means a reusable CLI or Docker-based interface is defined and usable across Decathlon repositories while accommodating future ARA changes with reduced breaking-change risk.
