This is a combination of 5 commits. . The first commit's message is: README template . This is the 2nd commit message: Synergy Scheduler Manager . This is the 3rd commit message: add initial setup.py . This is the 4th commit message: make the package installable 4 main changes: - define entry points for the provided managers - make this a real package by moving the code at the root of "synergy_scheduler_manager". - add missing dependencies - add constraint on oslo.* package versions This is needed because we use "oslo.*" namespaces when importing, and this is only available for oslo.config and oslo.messaging for versions < 2.0.0 . This is the 5th commit message: add cookiecutter template files Change-Id: I39609f07e38cfe27dd844bb277528b4a23049f9d
