Fix python35 job failures

- Installation of the cryptography module fails on Ubuntu Xenial
  because the libssl-dev package needs to be installed first, so we
  add this to other-requirements.txt

- inspect.getargspec()` was deprecated in Python 3.0 and will be removed
  in 3.6 (ETA late 2016). From Python 3.5 it started throwing a deprecation
  warning which leds some tests failures.
