IMPALA-7201. Support DDL with LocalCatalog enabled

This fixes a couple issues with DDL commands when LocalCatalog is
enabled:

- updateCatalogCache() gets called after any DDL. Instead of throwing an
  exception, we can just no-op this by returning some fake result.

- In order to support 'drop database' we need to properly implement the
  various function-related calls such that they don't throw exceptions.
  This changes them to be stubbed out as having no functions.

- Fixes for 'alter view' and 'drop view' so that the underlying target
  table gets loaded by the catalogd before attempting the operation.
  Without this, in the LocalCatalog case, the catalogd would only have
  an IncompleteTable and these operations would fail with "unexpected
  table type" errors.

With this patch I was able to run 'run-tests.py -k views' and 3/4
passed. The one that failed depends on HBase tables, not yet
implemented.
