ucp | create a local fetch directory if it doesn't exist - errors out.

[vvb]

When scheduler_provider = "ucp-swarm", the following error is seen

TASK: [ucp | create a local fetch directory if it doesn't exist] **************
failed: [cluster-node1 -> 127.0.0.1] => {"failed": true, "parsed": false}
[sudo via ansible, key=pinebvdaownqyquvfpxaengckhfixffn] password:


FATAL: all hosts have already failed -- aborting

[vvb]

with ansible 2.0, the error msg is clearer..

TASK [ucp : create a local fetch directory if it doesn't exist] ****************
fatal: [cluster-node1 -> localhost]: FAILED! => {"changed": false, "failed": true,
 "module_stderr": "sudo: a password is required\n", "module_stdout": "", "msg": "MODULE FAILURE", "parsed": false}
