+1. It's not necessary to give 2 different syntax but with same meaning. Just 
define the most suitable one.

    Hi,

    +1 for `FLUSH ALL` syntax.

    `FLUSH` and `FLUSH sg` are the existing syntax of the current standalone 
version.
    If we execute `FLUSH ALL` on standalone IoTDB, it can be equals to `Flush` 
command.
    `flush cluster` sounds meaningless for standalone IoTDB.

    Best,
    Haonan Hou
