WOPI - new documents create button (from template or not)

This ticket was created based on Feedback received from Bermuda Monetary Authority that is an existing client.

 

Users want to add new Word, Excel, and PowerPoint documents to existing or new Nuxeo documents with minimal configuration. The ideal scenario would be:
 

1. 
   Adding an option on the document page to create a new blank document in any O365 supported format.
2. 
   Modifying or introducing a new dropzone form that allows users to create new O365 files instead of uploading them.
3. 
   Creating a standard template directory (/Domain/0365/templates) where users can upload O365 document templates using a new Nuxeo document type called "O365 template."
4. 
   Adding a button that, when clicked, triggers a dialog for selecting a template (or just blank document) and either creating a new document or attaching a document created from the template to an existing nuxeo document. Users should then be redirected to the O365 website to complete the task.
5. 
   Allowing filtering of templates by providing a reference to a JavaScript function that takes the current folder/document path, user, and template name as inputs and returns true or false to determine whether the template can be used in this context or not.
