- Added static order by tests to test_queries.py and QueryTest/sort.test
- test_order_by.py also contains tests with static queries that are run with
multiple memory limits.
- Added stress, scratch disk and failpoints tests
- Incorporated Srinath's change that copied all order by with limit tests into
the top-n.test file
Extra time required:
Serial:
scratch disk: 42 seconds
test queries sort : 77 seconds
test sort: 56 seconds
sort stress: 142 seconds
TOTAL: 5 min 17 seconds
Parallel(8 threads):
scratch disk: 40 seconds
test queries sort: 42 seconds
test sort: 49 seconds
sort stress: 93 seconds
TOTAL: 3 min 44 sec

There was race when the catalog was invalidated at the same time a table
was being loaded. This is because an uninitialized Table was being returned
unexpectedly to the impalad due to the concurrent invalidate.
This fixes the problem by updating the CatalogObjectCache to load when
a catalog object is uninitialized, rather than load when null. New items can
now be added in a initialized or uninitialized state; uninitialized objects
are loaded on access.
Also adds a stress test for invalidate metadata/invalidate metadata <table>/refresh
In addition, it cleans up the locking in the Catalog to make it more
straight forward. The top-level catalogLock_ is now only in CatalogServiceCatalog
and this lock is used to protect the catalogVersion_. Operations that need to
perform an atomic bulk catalog operation can use this lock (such as when the
CatalogServer needs to take a snapshot of the catalog to calculate what delta to send
to the statestore). Otherwise, the lock is not needed and objects are protected by the
synchronization at each level in the object heirarchy (Db->[Function/Table]). That is,
Dbs are synchronized by the Db cache, each Db has a Table Cache which is synchronized
independently.
