IMPALA-9962: Implement ds_kll_quantiles_as_string() function
This function is very similar to ds_kll_quantile() but this one can
receive any number of rank parameters and returns a comma separated
string that holds the results for all of the given ranks.
For more details about ds_kll_quantile() see IMPALA-9959.
Note, ds_kll_quantiles() should return an Array of floats as the result
but with that we have to wait for the complex type support. Until, we
provide ds_kll_quantiles_as_string() that can be deprecated once we
have array support. Tracking Jira for returning complex types from
functions is IMPALA-9520.
