Currently, VXLAN VLAN-VNI mapping is 1 to 1 mapping and 1 entry for 1 mapping.
Suggest to support range-based mapping in 1 config entry.
Syntax example
set int vxlan vxlan1 vlan-to-vni 2-4094 vni 10002-14094
which means "vid 2 maps vni 10002, vid 3 maps vni 10003, and so on"
As I tested it it worked fine
set interfaces vxlan vxlan0 vlan-to-vni 30 vni '10030'
set interfaces vxlan vxlan0 vlan-to-vni 35-40 vni '10035-10040'
