Also fix a stale comment in the avro scanner header.
The main work here is to fix the handling of empty result sets in the
test result verifier. This is a problem because we wanted to verify
that the results in the test file were a superset of the rows
returned, and this was thrown off by superflous '' rows in the expected
and actual result sets.
The basic problem is that the way test file sections
was parsed conflated an empty result section with non-empty result
section that had a single empty string. I.e.:
---- RESULTS
====
vs
---- RESULTS
====
both got resolved to [''].

test_load was using /tmp as the staging directory, which did not cleaned up in Isilon,
leading to a build failure. This patch does the following:
- use /test-warehouse as the staging directory.
- replace calls to the hdfs commandline with calls to the in-house hdfs client.
- cleanup the test file and remove duplicates.
Additionally, a new method is introduced in the hdfs client to simulate hdfs dfs -cp, i.e,
it does a get and a put to mimic the hdfs command line's semantics.

This patch introduces changes to run tests against Isilon, combined with minor cleanup of
the test and client code.
For Isilon, it:
- Populates the SkipIfIsilon class with appropriate pytest markers.
- Introduces a new default for the hdfs client in order to connect to Isilon.
- Cleans up a few test files take the underlying filesystem into account.
- Cleans up the interface for metadata/test_insert_behaviour, query_test/test_ddl
On the client side, we introduce a wrapper around a few pywebhdfs's methods, specifically:
- delete_file_dir does not throw an error if the file does not exist.
- get_file_dir_status automatically strips the leading '/'

This change adds Impala support for LOAD DATA statements. This allows the user
to load one or more files into a table or partition from a given HDFS location. The
load operation only moves files, it does not convert data to match the target
table/partition's file format.
