tests: Add tests for BGP link-bandwidth and weighted ECMP

Implement tests to verify BGP link-bandwidth and weighted ECMP
functionality. These tests validate one of the primary use cases for
weighted ECMP (a.k.a. Unequal cost multipath) using BGP link-bandwidth:
https://tools.ietf.org/html/draft-mohanty-bess-ebgp-dmz

The included tests are:
Test #1: Test BGP link-bandwidth advertisement based on number of multipaths
Test #2: Test cumulative link-bandwidth propagation
Test #3: Test weighted ECMP - multipath with next hop weights
Test #4: Test weighted ECMP rebalancing upon change (link flap)
Test #5: Test weighted ECMP for a second anycast IP
Test #6: Test paths with and without link-bandwidth - receiver should resort to regular ECMP
Test #7: Test different options for processing link-bandwidth on the receiver
