Tests for HiveUtils methods that alter table/partition SerDe.
Take optional HiveConf (meant to reflect a session state) in HiveUtils metastore helpers.
A few small comments for SharkSemanticAnalyzer.
Add a helper function in HiveUtils that creates a UnionOI for a schema that includes partitioned columns.
Hive compliance: pass a NULL partition specification in HiveUtils#alterSerDeInHive() helper.

This indicates a non-partitioned table, and makes it slightly easier to deal with
NULLs/Options in the code.
New method in Utils that creates a PathFilter based on the snapshot of a given path.

Useful in computing deltas (i.e., new files/directories) for HadoopRDD loads.
