SupplierPart availability (#3148)

* Adds new fields to the SupplierPart model:

- available
- availability_updated

* Allow availability_updated field to be blank

* Revert "Remove stat context variables"

This reverts commit 0989c308d0.

* Increment API version

* Adds availability information to the SupplierPart API serializer

- If the 'available' field is updated, the current date is added to the availability_updated field

* Add 'available' field to SupplierPart table

* More JS refactoring

* Add unit testing for specifying availability via the API

* Display availability data on the SupplierPart detail page

* Add ability to set 'available' quantity from the SupplierPart detail page

* Revert "Revert "Remove stat context variables""

This reverts commit 3f98037f79.
