[HWKMETRICS-556] use TWCS for data_compressed table

We are also switching back to STCS for the data table because we are now doing
range deletes as part of the compression job. Eventually I think we'll switch
over to using what are essentially temporary tables for raw data that we just
drop once we are done writing to them and have compressed the data.
