Bug Description

When the cluster contains swift-metadata servers the os-services bootstrap-cluster.sh command fails with an error like this on a metadata node:

TASK [swift_hosts : Update genesis inventory with object disk list.] ***********
fatal: [192.168.0.41 -> localhost]: FAILED! => {"changed": true, "cmd": ["/root/os-services/osa/playbooks/roles/swift_hosts/files/swift_update_disk_lists.py", "-n", "192.168.0.41", "-i", "/var/oprc/inventory.yml.updating", "-o", "/var/oprc/inventory.yml.updating", "-d", "/tmp/swiftdiscovery/output.object.diskprep.192.168.0.41", "-t", "object"], "delta": "0:00:00.185053", "end": "2016-12-23 13:19:19.421014", "failed": true, "rc": 1, "start": "2016-12-23 13:19:19.235961", "stderr": "Traceback (most recent call last):\n File \"/root/os-services/osa/playbooks/roles/swift_hosts/files/swift_update_disk_lists.py\", line 155, in <module>\n main()\n File \"/root/os-services/osa/playbooks/roles/swift_hosts/files/swift_update_disk_lists.py\", line 150, in main\n process_disklist(args)\n File \"/root/os-services/osa/playbooks/roles/swift_hosts/files/swift_update_disk_lists.py\", line 104, in process_disklist\n sdp._read_dl_file()\n File \"/root/os-services/osa/playbooks/roles/swift_hosts/files/swift_update_disk_lists.py\", line 68, in _read_dl_file\n with open(self.dl_file, 'r') as fp:\nIOError: [Errno 2] No such file or directory: '/tmp/swiftdiscovery/output.object.diskprep.192.168.0.41'", "stdout": "", "stdout_lines": [], "warnings": []}

The root cause of the error seems to be that the inventory is trying to be updated with object disk lists on the metadata node when the metadata node does not have object disks.
