*Introduce new pojo classes to make the clone of pb object*
# RegionLoad -> RegionMetrics
# ServerLoad -> ServerMetrics
# ClusterLoad -> ClusterMetrics
*Introduce the {{Size}} to represent the size with specified unit*
*Methods cleanup*
*correct the InterfaceAudience*
# ReplicationLoadSource should be IA.Public
# ReplicationLoadSink should be IA.Public

> Project: HBase
> Issue Type: Bug
> Reporter: Chia-Ping Tsai
> Assignee: Chia-Ping Tsai

>
> {{ServerLoad}} and {{RegionLoad}} store the pb object internally but the
> bytebuffer of pb object may be reused in rpc layer. Hence, the {{ServerLoad}}
> and {{RegionLoad}} which saved by {{HMaster}} will be corrupted if the
> bytebuffer backed is modified.
> This issue doesn't happen on branch-1.
> # netty server was introduced in 2.0 (see HBASE-17263)
> # reusing bytebuffer to read RPC requests was introduced in 2.0 (see
> HBASE-15788)
