Code Issues Proposed changes

Use hypervisor_hostname for host name 

In Nova, "service host" is where nova-compute is running and
"hypervisor_hostname" represent each physical node that the virt
driver reports. They can be different in some of the hypervisor
backends where one nova-compute corresponds to multiple physical
nodes. Blazar holds the values separately as "service_name" and
"hypervisor_hostname".

Since Nova aggreate is associated to nova-compute service, we used
"service_name" with aggregate solution for reservation. However, now
we can use "hypervisor_hostname" with placement api solution for
reservation. This patch switches it.
