Bug Description

On initialization schema will set the default RT for all RI:

https://github.com/Juniper/contrail-controller/blob/R2.21.x/src/config/schema-transformer/to_bgp.py#L640

At this point we loose all data path that involves a router (E/O via router, SNAT)

Later, in the initial IFMAP poll, the RT are added back to RIs and the traffic is restored.

Observed on R2.21.x

The problem is happening because the route targets of the connected logical routers are not added to routing instances when schema transformer starts. They are added later. We are working on the problem.

Fix is to update only the new route targets and remove
all stale route targets after reint.

Also contrail python packages are cleared from the pip cache
before creation of test virtual enviroiment to make sure
the virtual enviroinment is installed with the newly built
python package.
