Description

Although IoTDB has a check style specification, the unification of the current code format is still not well controlled, such as Missing spaces[1][2] or the most typical problems of mixing 2-space and 4-space in indents [3][4], etc.

So, I would like to propose using Spotless for IoTDB coding style check, the detail can found in the discussion [5].
