Added new 'AUTO' format to workspace CLI to allow importing extra files types

[osuleiman]

This is a minimalistic update to allow the new format 'AUTO' to be used which is available on the [REST API](https://learn.microsoft.com/en-us/azure/databricks/dev-tools/api/latest/workspace#notebookexportformat:~:text=Description-,AUTO,-(Public%20Preview) as part of the release of workspace files.

This update will allow the importing of all file formats and not only the initial list of files (SOURCE, HTML, JUPYTER, DBC).

Introduced the addition of the flag "are_workspace_files" or "wf" for import_dir command to help switch between current functionality, and the importing files within a directory using their original extension.

Man, great PR!
This will help a lot users that wants to keep .py module files with their own extension.

This is really important.
Trying to move init-scripts files from DBFS to Workspace, but can't do it programmatically.
Have several scripts that are uploaded from an automated pipeline, which are now being uploaded manually.
Not optimal at all.

Hi, I see that I approved the changes on July 6th, but that was not intentional and I was not aware of this. Can you please defer the review to someone else? Thanks. Br Jesper
