Redhat OOO: EVPN VXLAN Provisioning Missing

In Redhat OOO (OSPD) we need to add support for EVPN VXLAN. Details of the implementation mentioned below along with Server manager implementation details .

Steps to be added:
Step 1: Following 2 lines need to be added in /etc/contrail/contrail-vrouter-agent.conf
       agent_mode =tsn-no-forwarding

       # TSN list - list of tsn nodes working in active/backup mode
       # when agent runs in tsn-no-forwarding mode
       tsn_servers=<control-data-ip of tsn1> <control-data-ip of tsn2>
       Sample: tsn_servers = 172.16.180.101 172.16.180.103

Step 2. Restart supervisor-vrouter

Step 3: Change the Type of TSN node from Hypervisor to Tor Service Node

How it is implemented in SM:

Under server section they have added 2 more parameters. 1. tsn_evpn_mode 2. tsn_server_list. When tsn_server_list set to true we set5 agent_mode as tsn-no-forwarding in contrail-vrouter-agent.conf . Also when tsn_evpn_mode is true , tsn_server_list is updated as tsn_servers in all the TSN nodes.
