Review comment:
       It is very strange to use the `ConfVars.TRY_DIRECT_SQL` configuration in 
client side.
   
   We could have used the same patterns like in `get_table_statistics_req`:
   - HMSHandler has only a single method to call on `getMS()`
   - ObjectStore could use some `GetHelper` implementation to decide on the 
actual implementation (directsql/datanucleus)
   - If we want to make sure that the size of the Thrift request is not too 
much we might have another configuration on client size like we do with 
`BATCH_RETRIEVE_MAX`
