Ensure Slave Instance can be instanciated on other software release instance (thanks to Instance Node)

* show allocation supply state
* InstanceTree_getSoftwareProduct also return release and type variations

* Allocation Supply Module draft
* allocation supply is... a supply
* draft Allocation Supply Line/Cell
* Allocation Supply Line view
* Allocation Supply Line

Compare behaviour outsied my dev instance

This is a hack incompatible with virtual master standalone logic.
Better design is needed

We use Software Project Release Variation instead

* do not create the open order if the software product can not be found
* set price on the open order
  it requires to create a temp sale order, where sale supply is automatically applied

* XXX support Open Order Cell
* XXX constraint must also support Cell

* WIP test for variated resource on open order...
* check variation stock
* check accounting
* check transaction total_price

* create Software Type portal type
  It is a variation of a Software Product
* rename Software Type to Software Product Type Variation
* add Software Product Release Variation portal type
* force default use/base_contribution on Software Product
  Didn't find another way to do it (init script requires data migration)
* require Software Product to have at least one Type and one Release

* add hardcoded test to expand an open order
* no need to use hardcoded organisation...
