This is an alternative to hashicorp#332, adding an option that enables the user to implement graceful shutdowns for Apply and Destroy operations. Rather than adding an option that changes the behavior of the input context, we instead add an option that specifically sends an interrupt to the terraform process. The input context behavior remains unchanged. This requires the caller to do a bit more orchestration work for timeouts, but keeps context truer to the "abandon work" intent. This also allows users to force quit _even if_ they are in the middle of a graceful shutdown, rathern than having one behavior mutually exclusive with the other.

I think SIGINT is not available in Windows and that's what's making the test to fail 🤔

I'm wondering why cmd_linux can't be used for macos as well?

I've made cmd_linux -> cmd_unix as the implementation should work in all unix systems

All unix platforms should support SIGKILL and SIGINT. This change uses the implementation of cmd that sends SIGKILL and SIGINT in all unix platforms. The list of platform tags is extracted from go/build/syslist.go and emulates what's done by the unix build tag introduced in go1.19.
