ImportError: cannot import name 'JSONDecodeError' in Python 3.4 #4

In Python 3.4, the orchestrator cannot start because of the following exception:

Traceback (most recent call last):
  File "/usr/bin/unicorn", line 4, in <module>
    __import__('pkg_resources').run_script('alto-unicorn==0.1', 'unicorn')
  File "/usr/lib/python3.4/site-packages/pkg_resources/__init__.py", line 745, in run_script

    from json import JSONDecodeError
ImportError: cannot import name 'JSONDecodeError'

I think it is because JSONDecodeError is introduced since Python 3.5. So it is not compatible with Python 3.4 or lower.
