Impala incorrectly returned NULLs in the "Max Size" column of the SHOW
COLUMN STATS result when executed through the HS2 interface. The issue
was that the column was specified to be type INT in the result schema,
but the actual type of the contents that we inserted into it was
"long". The reason why this is not an issue in Impala shell is because
we stringify the contents without inspecting the metadata for beeswax
results.
The issue was fixed by changing the type from INT to BIGINT.

- Moves the test into compute_stats.py
- Changes some test classes in compute_stats.py to inherit from
ImpalaTestSuite and not from TestComputeStats because that
will cause all tests in TestComputeStats to be run in the
subclasses again (redundantly).
- Clean up and add more coverage to testing incremental stats on
HBase which was probably broken in this commit 6b32ff06.
- Fixes a side effect that the original test had for testing
incremental stats on HBase. It computes stats on a functional
table which was not supposed to have stats.
Testing: Ran compute_stats.py on exhaustive locally in a loop 10 times.
Did a private hdfs/core run.

Additionally, this patch also disabled the hbase/none test dimension if the
TARGET_FILESYSTEM environment variable is set to either s3 of isilon.
