[feature]: support insert data by sql

[joyant]

What about:

INSERT INTO
    tb_name
        [TAGS (tag1_value, ...)]
        [(field1_name, ...)]
        VALUES (field1_value, ...) [(field1_value2, ...) ...]

1. Insert one record with function now(), the timestamp is always in the first position.

INSERT INTO d1001 tags("sh", "1.1.1.1") VALUES (now(), 10.2, 219, 0.32);

2. Insert multiple records with time, I think adding comma is better.

INSERT INTO d1001 VALUES
('2021-07-13 14:06:32.272', 10.2, 219, 0.32), 
(1626164208000, 10.15, 217, 0.33),
(now()-1s, 1, 2, 3);

3. Specify column names when inserting data.

-- ts or timestamp ?
INSERT INTO d1001 (ts, current, phase) VALUES (now(), 10.27, 0.31);

4. Allow table creation during insertion ？

I think it is difficult to define the type of fields in insert statement. So not allow table creation during insertion.

Steps:

1. create table(#1010 )

create table if not exist cpu 
(
    host tag,
    ip tag,
    load last,
    temperature max
);

2. insert data

-- single
INSERT INTO cpu (timestamp, host, ip, load) VALUES (now(), "sh","1.1.1.1",4);
-- batch
INSERT INTO cpu (timestamp, host, ip, load) 
VALUES 
(now(), "sh","1.1.1.1",4),
(now(), "sh","1.1.1.2",5),
(now(), "sh","1.1.1.3",4),
;
