--------------------------------

             Summary: [C++] Add variadic string join kernel
                 Key: ARROW-12709
                 URL: https://issues.apache.org/jira/browse/ARROW-12709
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Ian Cook


Similar to SQL's {{concat}} and {{concat_ws}}. Should take 0, 1, 2, ... string arrays and an optional separator (default empty string) and concatenate them together, returning a string array. Should also accept scalar strings and recycle their values.
