18-13 config authentication server failover

Description
This command is used to configure the authentication server failover function. When authentication
server fails, administrator can configure to:
* Use the local database to authenticate the client. The switch will resort to using the local database to
authenticate the client. If the client fails on local authentication, the client is regarded as un-
authenticated, otherwise, it authenticated.
* Pass authentication. The client is always regarded as authenticated. If guest VLAN is enabled,
clients will stay on the guest VLAN, otherwise, they will stay on the original VLAN.
* Block the client (default setting). The client is always regarded as un-authenticated.
