Project fetching updates

[iLLiCiTiT]

Changelog Description

Functions get_project and get_projects now do support to get 'productTypes' with other fields.

Additional review information

If productTypes are requested in fields then API uses GraphQl to get list of projects instead of projects endpoint.

Because data from graphql and REST are not 1:1 matching it was necessary to implement some conversion of the data to keep unified structure (e.g. 'bundle').

Testing notes:

1. Function get_project_product_types still works and returns product types used on project.
2. Using get_project and get_projects with {"productTypes"} in fields does return the projects with productTypes.

It returns productTypes, but where they are coming from? They are not in Anatomy.

That is set of product types used on the project.
