[tracker/wip/carlosg/domain-ontologies: 117/124] libtracker-common: Add domain ontology key/api to get expected miners

    libtracker-common: Add domain ontology key/api to get expected miners
    
    This is purely a hint, and people may still run things manually or perform
    updates against this domain ontology themselves. Will be useful so we don't
    autostart more miners than necessary through the libtracker-control API.
