IMPALA-7140 (part 7): small fixes to enable most queries on HDFS tables
This is a grab-bag of small fixes necessary to get most queries on HDFS
tables passing with the correct plans:
* Change the loading of tables to check for other table types before
checking for FS tables, since without specific checks against
various properties, other tables may look like FS tables and try to
instantiate LocalFsTable incorrectly.
* Return -1 for extrapolated row count -- the previous 0 value was
convincing the planner that it had a valid value.
* Fix up the handling of BuiltinsDb so that we don't depend on
ImpaladCatalog to have been loaded in order to instantiate it.
* Properly handle the case where all partitions are pruned by a
predicate.
With this change, about half of the tests in PlannerTest pass. The tests
that don't pass all rely on views, HBase tables, etc.

> Priority: Major
> Fix For: Impala 3.1.0

>
> 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.
