Support user-defined variables. After this PR, we can use `set @a = xx` to define a user variable and use it in the query like `select @a`. the changes of this PR: 1. Support the grammar for `set user variable` in the parser. 2. Add the `userVars` in `VariableMgr` to store the user-defined variables. 3. For the `set @a = xx`, we will store the variable name and its value in the `userVars` in `VariableMgr`. 4. For the `select @a`, we will get the value for the variable name in `userVars`.
