[ISSUE] workspace import fails if simplejson is not installed

[jdavidheiser]

Description The Databricks API requires base64 encoded notebook content when using the import_ method to import files to the Workspace. The standard library json package fails when running json.dumps on bytestrings. The requests package uses simplejson if it is installed, and simplejson can handle bytestrings.

Reproduction Do the following in an environment without simplejson installed:

c = WorkspaceClient()
c.workspace._import(path=<your_path>, content=base64.b64encode("content".encode()))

Expected behavior The databricks SDK should probably include simplejson as a requirement, or the API should accept unicode encoded data.

Is it a regression? No, this has always been broken.
