xraycli: add support for `-f rows`

`-f rows` - will output
```
> xraycli -f rows /test-app/itable  
-------------------- 
a:  1                
c:  3                
b:  2      
---------------------
a:  1                
c:  3                
b:  2      
```
 and will replace `-f itable`
can print `row_index` if `pk` not exists


`xraycli` will automatically print with `-f rows` tables that not fit to screen
