docs: Yosai consolidates rememberIdentity, an overloaded method in java,
          to a method that will use an identifier-else-account logic.
  
          Remembers a subject-unique identity for retrieval later.  This
          implementation first resolves the exact identifying attributes to
          remember.  It then remembers these identifying attributes by calling
              remember_identity(Subject, IdentifierCollection)
  
          :param subject:  the subject for which the identifying attributes are
                           being remembered
          :param authc_token:  ignored in the AbstractRememberMeManager
          :param account_id: the account id of authenticated account
