Description

Currently MiniOzoneCluster creates almost identical datanodes, based on global config and few datanode-specific properties:

• numDataVolumes
• datanodeReservedSpace
• dnLayoutVersion

The goal of this task is to introduce a factory to create datanodes for MiniOzoneCluster.

This would allow customizing each datanode (e.g. different number of volumes, different amount of reserved space, etc.), while also further cleaning up the global MiniOzoneCluster.Builder interface.
