Add support for multitenant FortiClient EMS deployments 7.0.8

When FortiClient EMS multitenancy is configured, a FortiClient EMS site is no longer unique using its serial number alone. The FortiGate configuration for FortiClient EMS connectors and related diagnostic commands have been enhanced to distinguish EMS sites using their serial number and tenant ID.
