Generates the P2Artifact after binary is published
Browse files Browse the repository at this point in the history 
Currently we generate the P2Artifact (+ IArtifactDescriptor) at time
where the output stream is requested, that has the problem that the file
actually do not exits at this point and we can not calculate the
checksum for feature root artifacts.

This postpones the creation to the stage where the file is already
published.
