Review request for pig, Cheolsoo Park and Daniel Dai.
Changes
-------

Updated patch. Had done some minor fixes. Also created tez staging dir in FileLocalizer relativeRoot directory.
Bugs: PIG-3742
    https://issues.apache.org/jira/browse/PIG-3742
Repository: pig
Description
-------

Changes made:
1) Converted the relevant MR settings to equivalent Tez settings and set them on AM, Vertex and Edge.
2) Moved the util and helper classes (SecurityHelper and TezCompilerUtil) to a util package. Does not show up cleanly in review board. Will be doing a svn mv while committing.
3) Fixed a issue with 1-1 edge in orderby while running pigmix where parallelism was not reflected in the second edge when the parallelism of first vertex changed after input split calculation. Also made POIdentityOutTez work with shuffle input as well when trying to test performance with 1-1 ege or shuffle edge with round robin partitioner. Shuffle edge with round robin partitioner or hash partitioner was very bad compared to MR. Even with 1-1 edge, performance is bad for L10.pig which orders by multiple columns. Still need to work on order by performance. Hoping unsorted shuffle with TEZ-661 might make it better.
