Description

Propose to rename 2 classes in package org.apache.hadoop.ozone.ksm

• MetadataManager -> KSMMetadataManager
• MetadataManagerImpl -> KSMMetadataManagerImpl

this is to avoid confusions with ozone metadata store classes, such as MetadataKeyFilters, MetadataStore and MetadataStoreBuilder etc.
