Sync specific folders in email provider

The main goal of syncing emails just from specific folders is to prevent emails with sensitive information to be synced to FunnelBud and added to Contact record and/or Opportunity.

To do that we need to create subfolders in Outbox and Inbox and sync them into FunnelBud.

If we decide to sync email to Funnelbud we just need to move that email to the relevant subfolder.
