- 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 patch handles a corner case we for some reason have not run into
yet. With the new container operational data it was triggered almost
immediately, so let's add some basic guards around it and return None

Add a helper that lets you call a Python function (or lambda) in the
context of a network samespace.
Example:
with infamy.IsolatedMacVlan("eth0") as ns:
res = ns.call(lambda: subprocess.run(["ip", "link"],
capture_output=True))
print(res.stdout, f"\n[exitcode:{res.returncode}]")
The call to subprocess.run will be executed in the context of the
network namespace, and thus only list "lo" and the "iface"
macvlan.
The return value of the function passed to ns.call() is passed back
over a multiprocessing.Pipe, which requires that the object be
"picklable". This is true for most objects (even more complex ones
like the CompletedProcess object seen in the example above). Some
notable exceptions are things like file objects, sockets, etc.
The setns(2) syscall is unfortunately not available in current
versions of Python shipped with neither Ubuntu nor Alpine at the time
of this writing. Therefore, shoot from the hip, assume that we're
running on an x86_64 CPU, and just hotwire the syscall directly with
some constants we found in a dumpster.
A very limited part of the YANG model is implemented so far, basicly it is OSPFv2 with multiple areas and you can change timers
for the interfaces. Limited operational support.

* sniffer did not work correctly
* links did not come upp as quick as in qemu
* must_reach in netns was to narrow, increase timeout
* add wait function to handle poll
The netconf-client Python lib currently does not support the <get-data>
RPC. This commit adds a local extension to the Device class which can
be upstreamed at a later time.
Also some added comments and disabling of pylint warnings.

This first version reliles on netcat (nc), mostly because that's what I
could figure out how to run in a netns. A better way would be to have a
full SsdpClient that can collect query responses properly and log all
devices found.
This, however, will do fine for verifying SSDP on/off functionality.
