  1. [Feature] Automatically create tablet when create table 

    Specfiy the tablet num when create table is very noisy.
Many users can not know how to give a right hint.
The pull request try to eliminate the pain to specify the num.

1. If the table is created from scratch, the tablet num will be
equal to the number of backends.
```
CREATE TABLE `test_table2` (
    `pk1` bigint(20) NOT NULL COMMENT "",
    `pk2` date NOT NULL COMMENT "",
    `v0` varchar(65533) NOT NULL COMMENT ""
) ENGINE=OLAP
PRIMARY KEY(`pk1`, `pk2`)
DISTRIBUTED BY HASH(`pk1`)
```

2. Add partition will use the last five partition size to calculate the tablet num.
```
ALTER TABLE test_table2 add partition p20220811 values less than("2022-08-11")
```
The num = total_size_of_last_five_partition / 10GB
