Consider replacing python3 setup.py develop with pip install -e .

[viniarck]

When executing python3 setup.py develop although the dependencies are frozen, looks like there's margin for some libs to have issues with eggs or wheels like it was shown on PR #27.

❯ kytos napps list

__init__.py)

If you install it with pip install -e . it also executes the develop mode and the same issue doesn't happen. We should consider replacing the python3 setup.py develop setup instructions in the future to avoid this type of surprise.
