imaging: send the PXE inventory to the inventory-server

The PXE inventory wasn't written to the inventory at all, except the
MACAdress.

This inventory is now send to the inventory-server configured in the
imaging-server configuration like an OCS inventory so that it can be
compatible with OCS servers.

We can also benefit of the entity/client mapping provided by the
inventory-server with no OCS agent installed.

If the inventory can't be sent for some reason (inventory-server down)
this won't stop the client to be up-to-date in the imaging database.
inventory: add a simple script to manage entities of the inventory backend

With this script you can list/add/remove entities.

On remove, all the entity's computers are assigned to the root entity.
If the computers continue to be mapped to the removed entity this entity
will be recreated and there will be duplicate computers in the inventory.
packaging: add pulse2-inventory-manage-entities to distribution
