Change subject: IMPALA-8021: Add estimated cardinality to EXPLAIN output

Bharath, thanks for the +2. Please hold off kicking off the final build until I 
verify that I've nailed all the test issues. Unfortunately, our pre-commit 
tests only catch one Python test failure per four-hour run, so it is a bit 
tedious to track down tests impacted by an EXPLAIN output change... I'l post 
here when the pre-review tests fully pass.

PS17, Line 210:       try (Scanner e = new Scanner(expectedStr);
> Just to be sure, there is no functional change here right?  As I understand
There is a functional change: one we need. The original version consumed two 
tokens per pass. Glance over at the left and look for the two a.next()/e.next() 
calls. Both consume a token. So, the original code didn't do what it claimed to 
do. The new code does work correctly.

I retained this fix even though the original impetus for the fix, adding 
filtering, was removed.
