feat(atomic): add experimental component for follow-up questions

[lbergeron]

SVCC-4341

This PR adds a new experimental component providing follow-up questions when a search query is performed. It relies on the Answer API to retrieve the questions, so the answer-configuration-id attribute has to be set on the component.

It can be added to a search interface this way:

<atomic-follow-up-question-list answer-configuration-id="YOUR_ANSWER_CONFIG_ID"></atomic-follow-up-question-list>

atomic-follow-up-question-list subscribes to the SearchBox state changes to detect when a new query is performed. When it happens, the Answer API is called to retrieve follow-up questions for the current query. The questions are then rendered by the follow-up-question-list-common and atomic-follow-up-question components.

At the experimental stage, follow-up questions are supported only for the search use case. Eventually, the request would be performed from headless and follow-up-question-list-common would be updated to make it easy to support other use cases (i.e., insight and IPX).
