contraception: use default consumables availability

[EvaJanouskova]

To be able to use the default consumables availability, we need:

(1) Use the item codes Item_Code_Avail instead of Item_Code (both in ResourceFile_Consumables_Items_and_Packages.csv).
(What about the availability of items for which we do not have similar item we could approximate the availability on?)

(2) Determine which items are essential.

@EvaJanouskova --it seems like this is now done?

[EvaJanouskova]

@tbhallett, No, it's not. Item_Code_Avail is prepared in the RF, not used in the model yet. And we do not distinguish non-essential consumables yet (except the pregnancy test).

I think this is sorted out with consumables module.

So we need to only define which items are (not) essential.
