As outlined in https://github.com/openfaas/faas/pull/873 and
in released 0.9.4 of the classic watchdog. This commit

traffic in a graceful way meaning we will not see connection
refused errors and in-flight HTTP requests still get a chance to
finish.
Also adds validation for upstream_url when in http mode.
