Add ActiveRecord::Relation#in_batches
`in_batches` yields Relation objects if a block is given, otherwise it
returns an instance of `BatchEnumerator`. The existing `find_each` and
`find_in_batches` methods work with batches of records. The new API
allows working with relation batches as well.
Examples:
Person.in_batches.each_record(&:party_all_night!)
Person.in_batches.update_all(awesome: true)
Person.in_batches.delete_all
Person.in_batches.map do |relation|
relation.delete_all
sleep 10 # Throttles the delete queries
end
