Can't delete a host using Physical Resource plugin

[Pablo Andres Fuente]

When you try to delete a host previously created, you should pass the host_id as a parameter. If you pass the host_id, you get an error when the PR plugin is trying to get the servers of the host that you are trying to delete (https://github.com/stackforge/climate/blob/master/climate/plugins/oshosts/host_plugin.py#L321) because the nova API needs the host name not the host id. If you pass the host_name, you get an error when the PR plugin is trying to get the host from the DB (https://github.com/stackforge/climate/blob/master/climate/plugins/oshosts/host_plugin.py#L325) because you need the host id not the host name.

    PR plugin uses host name to query Nova inventory

    Use host hypervisor_name instead of host id to query the Nova inventory
    to avoid not found errors.
