py-joblib: Update to 0.11
Notable changes since 0.9.3:
Add initial implementation of LRU cache cleaning.
Make the multiprocessing backend work even when the name of the main
thread is not the Python default.
pytest is used to run the tests instead of nosetests.
Refactored joblib.Parallel to enable the registration of custom

Joblib pickle format change: joblib.dump always create a single
pickle file and joblib.dump/joblib.save never do any memory copy
when writing/reading pickle files.
