Purpose of this commit is to add a new survey category for applicants. That
way surveys created and/or used through recruitment process are correctly
set in their own category allowing to filter them. When creating a new
recruitment only surveys linked to recruitment process are shown. Moreover
default values are propagated when creating new surveys so that they are
correctly configured by default as recruitment and invite-only surveys.
