[EVPN VXLAN]: [Build 4.1.0.0-35] Nova compute is running on TSN node

[chhandak]

On EVPN VXLAN cluster nova-compute is running on TSN node. SO, in turn, VM is allowed to launch on TSN node. Typically in OVSDV solution, we don't allow to launch VM on TSN node.

In EVPN VXLAN solution role of TSN has reduced just to DHCP/DNS server. So we want use TSN as compute as well or not has to be decided. Opening this bug as tracking one.
