Is your feature request related to a problem or challenge? Please describe what you are trying to do.
This is a follow-up of #1720.
We should support concatenating arbitrary number of arrays.
As rust does not support variadic function so far, we can refer to the concat function: https://github.com/apache/arrow-rs/blob/master/arrow/src/compute/kernels/concat.rs#L53
