As a User with proper permissions, I can upload a folder and nested folders using the Aspera connector

an end user needs to be able to identify files AND folders for upload using aspera. When folders are part of the upload, the hierarchy of nested folders is maintained.

AC:

• i see a way to identify files and folders for upload
• i can choose if the create should be automatic after upload is complete or if manual intervention is required (part of related ticket)
• (initial work) if a folder is uploaded, I cannot modify the file properties unless it's part of the "common metadata". (future iterations will address the bulk edit of properties)

Recent changes:

• if it's possible to know the number of files/folders while uploading, the label "In progress" should be replaced by X (number of files/folders uploaded) of XX (total number of files/folders)
• The dropzone now has 2 actions, one to upload files and another to upload folders, when clicked.
