[EPIC] Setting extension for TeamMail

[chibenwa]

Why

Enable a client to store per-user setting on the backend side.

Capability name: com:linagora:params:setting will unlock the Settings object (singleton), and with it the Settings/get and Settings/set methods.

Settings is a free floating String[String] map being set by the client. Our extension should include a registry of known usage from TeamMail mobile app, and usage.

Use cases

• Import my attachments into TDrive
• (Allow data collection for the knowledge graph) CF https://github.com/linagora/james-project-private/issues/562
• Automation: archival, cleanup trash and spam
• Always ask for read receipts
• Timezone
• Language
• Appearance?
• Enable PUSH notifications. (Can allow a user to fully forbid his data to transit through FCM...)...)
• Spam banner warning
• Email deletion warning
• attachment reminder warning
• Likely much much more...
