Bug Description
Currently all scheduler filters are run for each resource in a request, but for many filters the data doesn’t change during a request.
For example the AZ filter is pretty static, but expensive to run on a large system.
I will introduces a new attribute that allows filters to declare that they only need to be run once per request. The default behavior is left as being run for each resource.
Nova already support this feature. I'm now planing to enable nova use oslo filters, so I need first put this feature to oslo then sync up to nova
