Moving the overlay networks from traditional linux bridge to vlan awa…

…re bridge in leaf1. L3VNI broadcast domain remains as traditional bridge.

Removed L3VNI for blue VRF since blue VRF is used for asymmetric IRB demo.
Modified the L3VNI ids for green and yellow vrfs accordingly.
opi-test (host which is connected to Leaf1) now has 2 interfaces. First interface tagged in VLANs 10, 20 and 40. Second interface tagged in VLAN 50.
VLAN/VNI 10 is used to demonstrate L2 VXLAN.
VLAN/VNI 20 and 30 are used to demonstrate L3 VXLAN Asymmetric IRB.
VLAN/VNI 40 and 50 are used to demonstrate L3 VXLAN Symmetric IRB.
Added all the leaf1 configs as manual configs for now. Eventually these will be moved to grpc-test container as grpc calls.
