Summary: Combine test setup for datanode upgrade unit tests
Key: HDDS-11282
URL: https://issues.apache.org/jira/browse/HDDS-11282
Project: Apache Ozone
Issue Type: Improvement
Reporter: Ethan Rose
{{TestDatanodeUpgradeToScmHA}} was the first unit test for handling of a
specific datanode layout version. It works by starting just the minimal [SCM

This allows most fo the functionality that would be present in a
MiniOzoneCluster integration test but runs at the speed of a unit test.
The framework has since been adopted for testing other layout features in
{{TestDatanodeUpgradeToSchemaV3}} and {{TestDatanodeUpgradeToHBaseSupport}},
but the code has been copied each time. This Jira is to extract the common
setup code so that it can be re-used to test datanode layout features in the
future.
