This patch adds a 'location' column to the output of SHOW TABLE STATS /
SHOW PARTITIONS. This helps users understand the effects of ALTER TABLE
SET LOCATION commands, particularly for partitions, and is easier to
identify than the output of DESCRIBE FORMATTED.
Some existing tests in alter-table.test have been updated to include
checking the location output before and after a SET LOCATION
command. The tests in show.test have also been updated to check for the
location; all other tests that use SHOW [TABLE STATS|PARTITIONS] use a
generic regex to avoid overly verbose tests.

In the case, that a cached table was created in a version of Impala that
did not have the property for the cache replication factor, the loading
of the table will fail until the table is un-cached and cached again.
This patch fixes this behavior and ignores this missing parameter.

When a table is loaded in the catalog, we will now perform a check to
verify that the cache directive ID and cache replication factor is still
valid and the data is current.
If the cache directive does no longer exist, we issue a error message
and mark the table / partition as uncached. Furthermore, the replication
factor is updated with the information from the actual cache directive.
In the case of insert statement there is a special situation as the
catalog update is happening synchronously and will try to access the
cache directive information that might be stale. Thus in this insert
path, we catch the possible not found exception and reset the caching
information.
