We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Do not import `parsl` before requirements are setup
```
[annawoodard@midway001 parsl]$ python setup.py install
Traceback (most recent call last):
  File "setup.py", line 2, in <module>
    from parsl.version import VERSION
  File "/home/annawoodard/parsl/parsl/__init__.py", line 35, in <module>
    from parsl.executors.ipp import IPyParallelExecutor
  File "/home/annawoodard/parsl/parsl/executors/ipp.py", line 4, in <module>
    from ipyparallel import Client
ModuleNotFoundError: No module named 'ipyparallel'
```

Setuptools is supposed to take care of dependencies for us, but importing parsl in `setup.py` breaks that (because we require the dependencies by importing the parsl version from `version.py` before they can be installed). We should avoid this.
