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.
