Added support for Python 3.7.

Details:

* Added support for Python 3.7. This required increasing the minimum versions
  of several Python packages in order to pick up their Python 3.7 support:

  - `pyzmq` from 16.0.2 to 16.0.4 (While 16.0.4 works for this, only
    17.0.0 declares Python 3.6(!) support on Pypi, and Python 3.7 support is not
    officially declared on Pypi yet for this package).

  - `PyYAML` from 3.12 to 3.13 (see PyYAML issue
    yaml/pyyaml#126).
