It is better when manager does not need to care about calling data driver parse method but instead manager just instantiates data driver with raw data and then asks data driver for ready to use objects. Even more, it is necessary to encapsulate this logic into a data driver itself because which schemes we actually need (PartitionScheme, ConfigdriveScheme) depend on the manager's do_* method we use. Some do_* methods don't even need PartitionScheme or ConfigdriveScheme and a user who calls for example do_reboot method does not assume she needs to provide fuel-agent with partitioning data.
