Feature Request Group/Tag (named/unnamed) people -> filter for e.g. family members

Is your feature request related to a problem? Please describe.
When naming many people, it is hard to still keep an overview over all people and where you know them from. Therefore it would be nice to tag persons/clusters with groupnames. Like this you would be able to filter for persons you know from a sports club or filter just for your family members.

I think it would be also great to have the option to add a group label to unnamed people. So you don't know there name, but you know you have met them in a specific context (like a sportsclub).

The current alternative is to tag every picture, but I think it is a better solution to tag/group faces automatically instead of tagging manually every image.
