- Add a heriarchy to the mailbox: 0 is root, 1 is the top of information store
and almost every visible folder falls underneath
- Add systemidx for provisioning purpose
- Limit mailbox folder to the strict minimium - Outlook provisions the others
- Update REST backend provisioning code
Implement create_root_folder in mapistore Python and REST backend
Remove commented line
Hack: do not force specified folderID to be the same than curent context fmid
Return 'mails' as the default collection
Ensure 'type' is a key of restriction prior processing it
Remove auto-provisioning for now
Hack: Allow folder creation at root level (leverage REST create_root_folder impl)
