Bug Description

Respect origin vn attribute if it is more than 8M.

We need to import origin vn attribute when we enable service chaining
between multiple clusters.
Currently, we are ignoring this attribute if the route is coming in eBGP
connection.
In this bug, we amend this process so that we respect the value if it is more than 8M such as we are doing it in security group.

Treat VN index >= 8000000 as global

This is required for correct operation in multi-region scenarios with
service chaining. If there are 2 or more regions re-originating routes
for service chaining, we do not want to derive the origin vn from the
route targets of routes received from other regions. We want the global
controller to manage allocation of vn ids and trust received values if
they have been allocated by global controller.

Values greater than 8000000 are treated as global and are allocated by
the global controller. Need to disregard the ASN and compare only the
vn ids in this case.
