Change subject: [Java] Add Schema.getColumnById
......................................................................


Patch Set 1:

This was a super small change to simplify getting the columns by there id. I 
assumed since it was easy, small and used by Impala too I would just add it to 
the client.

It appears the id is a server side set value, while the index is just generated 
from the column order. I am not sure how/when they are different.

Given the feedback on this change that the columns ids are not meant for public 
use, I will drop this change and instead follow up at a later time to remove 
the exposure of column ids in the PartitionSchema classes (which is where they 
are exposed).
