Paul Rogers 360f88e207 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.
