   [NOTE]: # ( ^^ Provide a general summary of the request in the title above. ^^ )
   
   ## Is your feature request related to a problem? Please describe.
   
   The MFT API is missing some features required to implement the data management capabilities of airavata-django-portal.
   
   - delete file/directory
   - create directory/ies
   - update a file - this allows users to edit files in the gateway
   
   Possibly also (I consider these "nice to have" but aren't necessary):
   - move file/directory
     - this can be implemented by reading and writing a new file in the new location and then deleting the old file in the old location, but a move API could be more efficient
     - probably only need this for moving files/directories within the same resource
   - copy file/directory
     - similar comments to move, this can be implemented by reading and writing a copy of a file, but a copy API could be more efficient
     - for this we might want the ability to copy across resources. The use case is a user cloning another user's experiment and the inputs files are copied. If the source input files are on one resource but the experiment data directory is created on a different resource then copying across resources is needed.
   
   For reference, this is the minimal interface I want to implement using MFT APIs: https://github.com/apache/airavata-django-portal-sdk/blob/mft-integration/airavata_django_portal_sdk/user_storage/backends/base.py
   
   The MFT APIs support implementing all of these methods except for the following:
   
   ```python
       def delete(self, resource_path):
           raise NotImplementedError()
   
       def update(self, resource_path, file):
           raise NotImplementedError()
   
       def create_dirs(self, resource_path, dir_names=[], create_unique=False):
           """
           Create one or more named subdirectories inside the resource_path.
           resource_path must exist. dir_names will potentially be normalized as
           needed. The intermediate directories may already exist, but if the
           final directory already exists, this method will raise an Exception,
           unless create_unique is True in which the name will be modified until
           a unique directory name is found.
           """
           raise NotImplementedError()
   ```
