Due to the salting being applied to Python's `hash()` (see [1]), the
hash of an object is not stable across different Python processes. As
a result, neither are the topology mappings generated by networkx.
The upside of this is randomness that we get better test coverage over
time, especially on physical devices where the underlying hardware
could differ between ports, for example.
On the other hand, it can be very frustrating to track down a bug when
locial nodes are suffled around between phyical nodes on each
invocation of a test case.
Therefore, use a random seed by default, but allow the user to specify
a fixed value if they so choose. We then add a meta test that logs the
seed being used for the current suite - which means we can simply
copy&paste that value to rerun the suite (or single test) with the
same topology mappings.

- New helper class for container testing
- New helper class to urllib, Furl
Due to extremely weak Python-fu in the undersigned, this patch changes
the __init__.py file to add new helper classes for container tests.

This test use NETCONF to enable/disable SSDP, it then verifies that the
DUT responds to, or does not respond to, SSDP discover messages.

When running in the cloud, without KVM emulation, together with many
other tenants, it can take a very long time to boot the instances.
Therefore, add a meta test that will wait for all devices in the
physical topology to come up before exiting. This means that the
actual test cases that follow can assume that devices will answer
NETCONF requests.
