Bug in plugin SDK

Plugin simulator raises exception instead of providing collected measurements. Details:

python version - 3.8.1

Dynatrace plugin SDK - 1.183

Installation:

pip3.8 install plugin_sdk-1.183.163.20200203.165724-py3-none-any.whl --user

Running demo:

python3.8 -m plugin_sdk.demo_app

Starting plugin simulator in demo plugin directory:

cd ~/tmp/dynatrace/sdk/examples/demo_oneagent_plugin
~/.local/bin/oneagent_sim

it runs for some time

and after stopping with CTRL-C an exception raised:

^CPlugin simulator was stopped with a Keyboard interrupt
Traceback (most recent call last):
  File "/home/andriis/.local/bin/oneagent_sim", line 10, in <module>
    sys.exit(main())
  File "/home/andriis/.local/lib/python3.8/site-packages/plugin_sdk/plugin_simulator.py", line 154, in main
    _main(args)

    all_events = list(itertools.chain(results, statuses))
  File "/home/andriis/.local/lib/python3.8/site-packages/plugin_sdk/plugin_simulator.py", line 489, in _get_results
    yield MeasurementsEvent(m[0], m[1][1][1].measurements)
AttributeError: 'collections.defaultdict' object has no attribute 'measurements'

How to fix:

cd ~/.local/lib/python3.8/site-packages/plugin_sdk
$ diff plugin_simulator.py plugin_simulator.py.orig

You should use Python 3.6, as stated in documentation
