Add script to removed / clean release

[Nicolas-Delahaye]

When a new version is released, then we need to delete development version (SNAPSHOT) and release candidate (DEV).

Rules:
All SNAPSHOT release are removed (included in gh-pages@index.yaml)
ALL DEV (Release Candidate) are remove from vresion N-1 -> Example:
If Release 1.3.2 version -> 1.3.1-DEV-* will be deleted
If Release 1.4.0 version -> 1.3.x-DEV-* will be deleted
