WOPI integration - technical specifications, estimations & scope

The objective of this JIRA is to assess current situation with WOPI, Microsoft platform and our dev environment is ready to start implementation :

The feature covers 3 parts :
=> Access and work on any Office files in Nuxeo, from any browser on any device. Updates to documents are automatically saved in real-time.
=> Create Office documents (Word, Powerpoint, Excel, etc.) within Nuxeo rather than needing to create them on a machine then uploading.
=> Allow users to work together on the same file in real-time, allowing them to see all edits being made by internal colleagues or third parties, right as they're happening.

• Doc is still https://wopi.readthedocs.io/ + we should now have an integration environment + should explore differences w/ office 365
• We've been added to Microsoft CSPP Yammer group ( https://www.yammer.com/officeenterprisenda/#/threads/inGroup?type=in_group&feedId=7197423 )
• We should check that current JIRA tickets are exhaustive
• Usecases for nuxeo are also listed here for discussion : https://docs.google.com/spreadsheets/d/14y8_DN0hBPpiDO8kKiEHcxnJOqSDW3Ohcfrf_Hiylfk/edit?usp=sharing
