IMPALA-8181: Abbreviate row counts in EXPLAIN
A recent fix added node cardinality to the standard EXPLAIN output,
displaying a large number like 123456780 as 123.46M. This patch applies
the same fix to the remaining row count numbers: metadata, extrapolated
rows, etc.
Tests:
* Rebased PlannerTest .test files as needed for the new row count
format.
* Reran all tests to check for dependencies on the old format.

> URL: https://issues.apache.org/jira/browse/IMPALA-8181
> Project: IMPALA
> Issue Type: Improvement
> Components: Frontend
> Affects Versions: Impala 3.1.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Minor
>
> A recent change added plan node cardinality to the DESCRIBE output using a
> "metric" format: 123.46M instead of 123456789. This makes the output easier
> to read. Also, since all numbers are estimate, having seven or eight digits
> of precision is not very helpful.
> This ticket requests that the same formatting be used for the other places
> where the DESCRIBE output shows row counts: table stats, extrapolated row
> count, partition row counts, and so on.
