Cascading SI with Transitive network isn't working

Cascading SI with Transitive network isn't working

(verified on R2.1)

This is a topology.

Red Network <-> [SI_Red1] <-> [SI_Red2] <-> Transitive Network <-> <-> [SI_Blue1] <-> [SI_Blue2] <-> Blue Network

All SIs are transparent FW.

It looks like both of SI's right hand side routing instance exporting RT of transitive network, so routing get messed up, or
packet looping get happened.

Use correct SI name to add route-target

For transit VN, the route target of the primary RI should be added to the first
service RI (for left VN), or last service RI (for right VN). Earlier, we were
always adding it to the first service RI.

Adding the following tests to address the test gap

Scenario #1:
Left-VN — left-services — Transit-VN — right-services — Right-VN

Test cases:
Single instance – symmetric: same type of service on both left & right
1. in-network-nat
2. In-network
3. Transparent

Single instance – asymmetric: different services on left & right
4. left: in-network-nat & right: transparent
5. left: in-network & right: transparent
6. left: in-network & right: in-network-nat

Two instances – symmetric: right & left have a same type of services
7. transparent (2 instances)
8. in-network (2 instances)
9. in-network, in-network-nat
10. transparent, in-network-nat
11. transparent, in-network
