code: public AVQuery<T> whereContainsAll(String key, Collection<?> values) {
      conditions.whereContainsAll(key, values);
      return this;
    }
docs: Add a constraint to the query that requires a particular key's value match another AVQuery.
  This only works on keys whose values are AVObjects or lists of AVObjects. Add a constraint to
  the query that requires a particular key's value to contain every one of the provided list of
  values.
  
  @param key The key to check. This key's value must be an array.
  @param values The values that will match.
  @return Returns the query, so you can chain this call.
