route target lost on adding of Contrail nodes

[Illia Polliul]

We deployed env with one Contrail node and after that added 2 more Contrail nodes.
After addition of Contrail nodes, route target for our floating network stopped to be advertised to router.
As a result routes were not leaking into public table.

Here is how we provision route target:

/bin/sh -c python /usr/share/contrail-utils/add_route_target.py \
--routing_instance_name default-domain:admin:admin_floating_net:admin_floating_net \
--route_target_number 10000 --router_asn 64512 \
--api_server_ip 10.109.4.2 \
--api_server_port 8082 \
--admin_user 'neutron’ \
--admin_tenant_name 'services’ \
--admin_password 'g1qQiMBDQDzQbMCrg9WWcN9m' && touch /etc/contrail/prov_route_target-DONE’

This data was present in Contrail WebUI, but effectively it wasn’t applied. After we removed route target and added it back - everything started to work fine.
All Contrail services were reporting as “green” in Contrail WebUI. Contrail version is 3.0.2.1-4
