[aminekaabachi]

For the release of v0.0.4, we need to implement the following features:

• DBFS API : https://docs.microsoft.com/en-us/azure/databricks/dev-tools/api/latest/dbfs
• Libraries API : https://docs.microsoft.com/en-us/azure/databricks/dev-tools/api/latest/libraries
• Workspaces API : https://docs.microsoft.com/en-us/azure/databricks/dev-tools/api/latest/workspace

Please look at Clusters API implementation for an example.

You should Fork the project then issue a pull request.
