      Description

      One of the parts of this patch https://gerrit.cloudera.org/#/c/7065/ was cleanup of how descriptor tables were managed. As described in the commit message:

      Also: 
      - adds DescriptorTbl::CreateHdfsTableDescriptor to avoid having to create an entire DescriptorTbl during INSERT finalization (when only a descriptor for the output table is needed) - removes TQueryExecRequest.desc_tbl, there's already a home for it in TQueryContext.desc_tbl
      

      That cleanup should be independent of the larger patch so we could get it in separately.
