Is there any reason we dont support Redirect option for Exec Task

[Hoa Phan]

Hi,

I noticed a

org.gradle.process.internal.{ProcessSettings, ProcessBuilderFactory}

do not have options for https://docs.oracle.com/javase/8/docs/api/java/lang/ProcessBuilder.Redirect.html 

This causes Exec to fail if the underline script try to prompt for input.

Is there any particular reason we don't have the options?

Regards,

Hoa Phan.
