    Insert an individual indicator into the database.

    NOTE: Setting add_domain to True will always create a relationship as well.
    However, to create a relationship with an object that already exists before
    this function was called, set add_relationship to True. This will assume
    that the domain or IP object to create the relationship with already exists
    and will avoid infinite mutual calls between, for example, add_update_ip
    and this function. add domain/IP objects.
