FailOver mode - For globalStorage (session)
Is case of disaster recovery plan, or simply maintenance.
We would like a failover-mode in case of SGBd is'not reachable during exploration of SGBD.
After X attempt of connection or a manual switch form the manager, LLNG should be able to fail over session storage in a local File system.
Some time we want to update/check our SGB and we could have to bring those down for some minute/hours. We suggestion that when happen LLNG switch in failover mode, make a annoncement in the main login page ( FailOver mode ON - Some feature could be unavailable) and ask again for a new sessions.
To switch back in normal mode, the main globale storage should be available and be activate from the manager page by a config push to ensure every node of LLNG is in normal mode
