Use docker test server to run test, following instructions on
https://wiki.qt.io/Network_Testing. Verified on Ubunutu 18.04.
Several test failures due to network timeouts and inconsistent
configuration of FTP server and assumptions made in the tests.
However, the test is either way blacklisted, and the docker test
server is not in use yet.
