Remove deprecated and optional "family" field from details documents
On August 25, 2015, we added the optional "alleged_family"
and "indirect_family"
fields and deprecated the likewise optional "family"
field in details documents. As of yesterday, Atlas (#16961 (moved)), Globe (#16962 (moved)), and Compass (#17720 (moved)) stopped using the "family"
field and switched over to the new fields. It's time to finally remove the "family"
field from details documents.
