Improving folder management in Clowder GUI

[max-zilla]

On the UI, files have a 'Move' button to move into and out of folders, but the folders themselves do not have such a button. I don't know if the API supports adding a folder to another folder either. These are common operations that should be supported.

Current folder API features for reference:

• Create a new folder
• Move file in a dataset into a folder
• Move file in a folder back out into a dataset (no folder)
• Delete a folder
• Update folder name
• Get list of folder names and IDs by dataset ID

I'm commenting to hopefully boost this issue. My team would very much appreciate a way to move folders around within a dataset or to other parent or child folders through the UI or the API.
