Improve web app packaging

The current component packaging zip a the web app and a maven repository with runtime artifacts.
In both these folders we have almost the same artifacts so there are a lot of duplications.
Also all the artifact are copied into the maven repo such as sources,javadocs, bundle
We need to improve this to reduce the size of the zip and docker image.

One way would be to use the maven artifacts to launch the web app that is to add those artifacts in the web app class path.
