Summary: Improve the performance for region load and region count
related cost functions
Key: HBASE-25894

Project: HBase
Issue Type: Sub-task
Components: Balancer, Performance
Reporter: Duo Zhang
Assignee: Duo Zhang
Fix For: 3.0.0-alpha-1, 2.5.0
For a large cluster, we have a lot of regions, so computing the whole cost will
be expensive. We should try to remove the unnecessary calculation as much as
possible.
