[ADD] website_event_crm_questions: create leads from attendees

PURPOSE

are a powerful source of leads as they attract attention. This leads to leads
with good quality as they mark interest while gathering contact information
which allows to follow-up.

This merge aims at automating this process by automatically creating leads
based on user-defined rules.

SPECIFICATIONS

Include in generated lead description answers from attendees to questions
defined using the website_event_questions module.
