replay function supports specified column

[lizhou1111]

Replay function supports specified column.
For example:

drop stream if exists test_rep;
create stream if not exists test_rep(id int, time_col datetime64(3));
insert into test_rep(id, time_col) values (1, '2020-02-02 20:01:14')(2, '2020-02-02 20:01:15')(3, '2020-02-02 20:01:17')(4, '2020-02-02 20:01:20');
select *, from test_rep where _tp_time > earliest_timestamp() settings replay_speed=1, replay_time_column='time_col'

You have to specify the replay time column in the query through the replay_time_column settings
