Bug description:
  When adding a host to a segment masakari validates the provided
  hostname is a valid hypervisor name *1. But when masakari is mapping
  nova services *2 and servers *3 it uses the host attribute which may
  not necessarily match. It is common for the hypervisor entry to be a
  fqdn but service entry to be a bare hostname. In this situation both
  service and servers lookup fail and throw an IndexError.
