FIX: setuptools - use a context for installation so that all build ar…

…tifacts are cleaned up by default.

Pip installation is not cleaning up leftover 'build/' and 'edb_terraform.egg_info/' directories when installing from a local repo and might cause unexpected errors due to old build files being included in the final build.
When calling 'pip install . -vvv', logs show that it calls 'python setup.py egg_info' followed by 'python setup.py bdist_wheel'.
