`buildApolloGraphqlContainer` - investigate do we still need to implement logic of `scaffold()` function

[sabina-talipova]

Description

There is a function scaffold() in buildApolloGraphqlContainer.js that currently throws the new Error, because this function doesn't have any implementation. We should investigate, do we still need this function and should we implement it.
