Factor out as much of autopath into a subpackage as possible right now.
apw.Sent is not needed, we should see this from the rcode returned by
the middleware. See #852 on why this was needed.
Disable the tests for now as to not break the main build.
Put the autopath stuff in a separate sub package. Tests are still
included in the main kubernetes directory.
Next steps (after this is merged), is pulling the autopath handling
into the subpackage and fixing the tests.
Drop the interfaceAddr interfaces and just use a function. Cleanup
all fallout from that. Remove the use of global variables and cleanup
the tests a bit.
