Filters internal interface changed using now the RequestSpec NovaObject
instead of an old filter_properties dictionary.
In case you run out-of-tree filters, you need to modify the host_passes()
method to accept a new RequestSpec object and modify the filter internals
to use that new object. You can see other in-tree filters for getting the
logic or ask for help in #openstack-nova IRC channel.
