VLAN-based service with common customer edge VLAN ID

This feature introduces the EVPN-VXLAN VLAN-based service with a common customer edge VLAN ID. A VLAN-based service allows a one-to-one mapping of a single broadcast domain to a single bridge domain. Each VLAN is mapped to a single EVPN instance (EVI), resulting in a separate bridge table for each VLAN. Without VLAN translation, the customer edge VLAN must use the same VLAN ID.
