When setting global variables, such as `set global default_rowset_type=beta`, the operation is not correctly persisted. This CL change the fe meta version to 90. --------------- The main reason for this problem is that for the modification of global variable, we directly use Java's reflection mechanism to modify static member variables in `GlobalVariable` class. But in the persistence method of the `set` operation, we only persist the value stored in the `globalSessionVariable` variable, and this variable does not contain Global Variable. So I added a new OperationType: `OP_GLOBAL_VARIABLE_V2`, and added a `GlobalVarPersistInfo` class to record all changes.
