IMPALA-7140 (part 4): support creating descriptors for FS tables
This adds the relevant methods to convert LocalFsTable and
LocalFsPartition to thrift descriptors for consumption by the backend.
Unfortunately we cannot yet enable the planner tests, since they are
checking file counts and sizes as part of the explain output, and we
haven't yet implemented file info fetching in the LocalCatalog.
However, I was able to manually test this change by starting an impalad
with --use_local_catalog, connecting to it from the shell, and running
various EXPLAIN SELECT queries against tpch and functional tables. The
explain output is more or less as expected with the exception of missing
file info.

>
> This subtask tracks the work to build out basic read-only support for HDFS
> tables and views in the LocalCatalog implementation:
> - loading table schemas
> - loading partitions
> - loading file information from HDFS
> This work will be broken up into a number of patches to keep each piece
> reviewable. Once this subtask is complete we should be able to plan most
> simple read-only queries.
