Areas where ask_to_continue were removed should have results set with OVERRIDABLE

Areas where ask_to_continue were removed and replaced with add_message should be changed to use set_result with the level set to OVERRIDABLE and a new environment variable is put into place so the user can ignore that check or decide to have that check error out.
