Remove incorrect name filters from nodepool config

* modules/openstack_project/templates/nodepool/nodepool.yaml.erb:
Additional "performance" name-filter entries are removed from
providers where they are meaningless. With these in place, nodepool
was unable to find an appropriate flavor to build the associated
images.
