[MAIL] - Modify the direct trigger of sync capabilities for Zimbra and Partage
(Plugins) An update of the plugin tab Mail containing calls to Partage and Zimbra is required, if tick box of "usage of Orchestrator" is set within Supann backend configuration, the plugin should not perform anything itself.
It has been decided to create conditions within Renater and Zimbra plugins to handle this individually.
This allows more flexibility in the case of multiple servers being registered with different behavior required.
