IMPALA-11132 Front-end test PlannerTest.testResourceRequirements can fail
This patch addresses the potential row count over-estimation against HBase
tables
by capping the estimation by the row count when available from HMS.
Testing:
1. PlannerTest.testResourceRequirements passes with an update on the
cardinality
of the HBase tables involved.
2. Core test [TBD]
