The patch creates a utils directory that starts the process of moving various utils from neutron to neutron-lib. The utils are divided into the following: - file - all file related utilities - helpers - all kinds of helps - host - all host related utilities - net - all network related utilities NOTE: The patch follows the foundation header suggestions from: https://wiki.openstack.org/wiki/LegalIssuesFAQ#Copyright_Headers Change-Id: I4fe150d42a70a7ce5192c30ffaae52d1cf3d5d87
