Add search filters in the toolbar

Add the possibility to have other search filters in the resource list toolbar

Why is this important?

• This will let plugins define additional search filters on top of Name and Label in a resource list page

Scenarios

1. In the nmstate-console-plugin I would like to define other filters like IP search in the NMState list. This search will let the user filter the nmstate resources that are inside a subnet or by specific ips.

For now, using the props and some hacks we were able to change the Name search into an IP search but we would like to have both.
