Links don't show up in advertisements

[ibaldin]

@paul-ruth and @kthare10 report not seeing links in ads. Seems to depend on level of detail. requires investigation.

So I ran the test_abqm.py in fabric_cf/actor/test/. It produced abqm.graphml, which I then loaded as AdvertisedTopology. I'm seeing everything look normal - not clear how to reproduce missing links:

import fim.user as f
Backend MacOSX is interactive backend. Turning interactive mode on.
t = f.AdvertisedTopology(graph_file='abqm.graphml')
t.draw()
print(t)

The problem is in the latest network AM model switch nodes have type 'VM' instead of 'Switch'. Requires further investigation. This doesn't show up in the older models.
