The unique key which identifies this family within its row. This is the
same key that's used to identify the family in, for example, a RowFilter
which sets its "family_name_regex_filter" field.
Must match [-_.a-zA-Z0-9]+, except that AggregatingRowProcessors may
produce cells in a sentinel family with an empty name.
Must be no greater than 64 characters in length.
