Add tests that use a simple socket server instance that opens the port
and ignores all data in order to support testing when the socket timeout
is set and catching the exception triggered. Also test that when not set
that the request will continue to remain connected for a period of time
longer than the other test using a wrapper time limit process.
Includes some helper classes to black hole all requests by simply
listening using a socketserver but never accepting connections, and a
time limit function to allow wrapping actions with a time limit when
checking for blocking behaviour where the call should not return and
will need to be focibly terminated.
