for each IDeployer component, deployed deployable should not be unpacked if they are already unpacked.
For each IDeployer component when you deploy a deployable, it's unpacked in the work directory. When the server is restarting, deployed deployable are unpacked. This is not optimized.
So for each IDeployer component, deployable should not be unpacked if they are already unpacked (unless the server is starting with the clean option).
Maybe there should be a "--clean" option for deployable in order to delete all unpacked deployable.
