Display Pool entities containing search term when filtering
Display Pool entities containing search term when filtering

Fixes: https://github.com/oVirt/ovirt-web-ui/issues/1183

In the VM list, display the only those Pool entities which contain the current search term,
treat VMs, Pools and Pool entities the same way for all user types when filtering.
