topotests: new BFD test for multi hop features
Add a new test to cover the new features for multi hop BFD peers: - Test that we correctly receive TTL from protocol integration. - Check minimum TTL usage and 'show' command. - Check for passive mode. Signed-off-by: Rafael Zalamena <rzalamena@opensourcerouting.org>
