I am attempting to create a compute cluster using the Python SDK while sourcing a cluster-create configuration JSON file, which is how it's done for the databricks-cli and what databricks provides through the GUI.  Reading in the JSON as a Dict fails due to the assumption in the SDK that the arguments are of specific DataClass types, e.g.:

>       if autoscale is not None: body['autoscale'] = autoscale.as_dict()
E       AttributeError: 'dict' object has no attribute 'as_dict'

 This is the pattern of the call I'm making:

from databricks.sdk import WorkspaceClient

db_client = WorkspaceClient()
with open("my/path/to/cluster-create.json") as file:
    create_config = json.load(file)
db_client.clusters.create_and_wait(**create_config)

I've attempted to look around in the SDK to see if there's a bootstrapping function but haven't found anything.  I can certainly work around this situation, but it's a bit cumbersome so hoping the community can help point me to the magic-method I'm looking for.

Appreciated!
