Special characters in Session

When using Session to set storage group or create time series, special character in the path will cause an error in mlog.txt, which impacts the restart and recover of IoTDB.

session.setStorageGroup("root.tur_\n\t_bine");
session.createTimeseries("root.turbine.d1.s_\n\t_1", TSDataType.INT64, TSEncoding.RLE, CompressionType.SNAPPY);

It's better to reject these characters in the Session.
