[CMT][BUG] From oracle to CUBRID, the FK migration is not right.

1 Create tables in oracle
create table FKud( id nchar(10));
create table FKmain( id nchar(10));
alter table FKmain add constraint pk_main primary key(id);
alter table fkud add constraint fk_fkud_fkmain foreign key(id) references fkmain(id) on delete cascade;

create table fksn (id nchar(10));
create table fksnmain (id nchar(10));
alter table fksnmain add constraint pk_fksnmain primary key(id);
alter table fksn add constraint fk_fsn_fsn foreign key(id) references fksnmain(id) on delete set null;

create table fkno(id nchar(10));
create table fknomain(id nchar(10));
alter table fknomain add constraint pk_fknomain primary key(id);
alter table fkno add constraint fk_fkno_fknomain foreign key(id) references fknomain(id);

2 do migration goto step5
The FK of fk_fkud_fkmain display on update cascade, on delete cascade.
The FK of fk_fsn_fsn display on update cascade, on delete no action.
The FK of fk_fkno_fknomain display on update cascade, on delete restrict.

Expect result
The FK of fk_fkud_fkmain display on update no action, on delete cascade.
The FK of fk_fsn_fsn display on update no action, on delete set null.
The FK of fk_fkno_fknomain display on update no action, on delete no action.
