Hardening build pipine

[lyrixx]

ATM, our release pipeline is sub-optimal. If one artifact could not be build, all the pipeline is KO.

Use a "best effort" pattern

For each artifact, independently of others artifacts:

• build
• upload

so if one build fails, it does not impact all

Add support for pre-release

When we change some build option, if would be nice to be able to use pre-release.

So we must ensure:

• We can publish pre-release without impacting end user
• Our pipe line works as expected
