get_versions()

Extract versions of Python, fractal-server and cloudpickle.

This information is useful to check compatibility of two Python interpreters when running tasks: the current interpreter (which prepares the input pickles and orchestrates workflow execution) and a remote interpreter (e.g. the one defined in the FRACTAL_SLURM_WORKER_PYTHON configuration variable) that executes the tasks.
