   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] 
   (This section helps Arrow developers understand the context and *why* for this feature, in addition to  the *what*)
   
   a `SET` command to change the value in `config_options`
   
   **Describe the solution you'd like**
   A clear and concise description of what you want to happen.
   
   following what postgresql has except `[LOCAL]`
   https://www.postgresql.org/docs/current/sql-set.html
   
   assignment operator should support both `TO` and `=`
   value should support `single quoted string` / `number` / `bool` / `non space separate string`
   
   
   ```bash
   SET [VARIABLE] [TO | =] [VALUE | 'VALUE']
   ```
   
   e.g. 
   ```bash
   ❯ set datafusion.execution.batch_size = 1;
   
   ```
   ```bash
   ❯ set datafusion.execution.coalesce_batches to 'false';
   ```
   
   support alias `TIME ZONE` and `TIMEZONE` (same as postgrseql https://www.postgresql.org/docs/current/sql-set.html)
   ```bash
   ❯ set time zone = 1;
   ```
   
   note that this should return error for now as discussed in https://github.com/apache/arrow-datafusion/issues/3148#issuecomment-1226105182

   YES!  This will be awesome
   
   Note there is still some nonsense related to Config settings (e.g. see https://github.com/apache/arrow-datafusion/pull/3885#pullrequestreview-1152448744) but I think supporting the `SET` command will provide us that much more reason to unify the configuration story
