Currently neutron uses socket.gethostname() to determine hypervisor
names, but this implementation is not fully compatible with libvirt
driver which uses canonical name for hypervisor name.
This incompatibility causes an issue with root resource provider
detection if a deployment uses FQDNs as canonicanl names.
This change introduces the resource_provider_default_hypervisor option,
so that users can override the hypervisor name by the single option(*1)
instead of setting two list options(*2). This is especially useful if
the deployment has multiple bridges or interfaces.
