Export env vars that point to cloned path

[PI-Victor]

Export env variables with the name that was defined as alias in the config.yaml plus WORKSPACE.
e.g.: API_WORKSPACE
This env variable will have the full path to where we cloned the repository.

although, in hindsight, these variables might be shell session bound.
Their lifecycle might be over by the time jenkins would try to use them.

environment variables set with os.environ['TEST'] = 'test' are process bound, which means they are gone after the app finishes.
an alternative would be to use the python shell command to export them to the env.
