Pulp

Hi,

I'm running pulp in a Kubernetes cluster and sometimes python publications are failing with the error '[Errno 39] Directory not empty' , after some debugging the error leads to https://github.com/pulp/pulpcore/blob/master/pulpcore/tasking/storage.py#L60

pulp-cli:

# pulp python publication create --repository foo --version 4
..................Error: Task /pulp/api/v3/tasks/11b036e7-3799-4806-a29b-9a784b6f4857/ failed: '[Errno 39] Directory not empty: 'wheel''

worker log:

OSError: [Errno 39] Directory not empty: 'wheel'

One quick fix maybe ignore 'OSError' or pass 'shutil.rmtree(self.path, ignore_errors=True)' ref: https://docs.python.org/3/library/shutil.html#shutil.rmtree
