Description

Implement new built-in Impala string functions to pretty print time duration from an input of nanoseconds and pretty print a memory value from an input of bytes.

For example, pretty printing a duration of 2147483648 nanoseconds would output "2s147ms". Pretty printing a memory value of 32768 would output "32.00 KB".
