'os' has no attribute 'sched_getaffinity'

It would be nice if in the manager.py there was an exception value for threads as os.sched_getaffinity is not available on all nix systems. I'm running macOS for example and this fails. If I set it to a static value, it runs fine.

  File "/Users/Jeff/Documents/workspace/katana/env/bin/katana", line 11, in <module>
    load_entry_point('katana==2.0', 'console_scripts', 'katana')()
  File "/Users/Jeff/Documents/workspace/katana/env/lib/python3.7/site-packages/katana-2.0-py3.7.egg/katana/__main__.py", line 36, in main
    manager = Manager(monitor=monitor, config_path=args.config)

    "threads": len(os.sched_getaffinity(0)),
AttributeError: module 'os' has no attribute 'sched_getaffinity'

I added a try/except for the default. I'd prefer sched_getaffinity as it properly reports if the process is restricted in some way. The branch will fallback to using multiprocessing.cpu_count() if it isn't available, though. To my understanding, multiprocessing.cpu_count should be available everywhere.

Please let me know if that doesn't fix the issue. I was going to check back before closing the issue, but github closed it automatically because I said "should fix #8" in my commit message, haha.

Since I didn't hear back, I'm going to close this issue, as the problem appears to be fixed from my end.
