* fix: Allow terraform provisions to be gracefully cancelled
This change allows terraform commands to be gracefully cancelled on
Unix-like platforms by signaling interrupt on provision cancellation.
One implementation detail to note is that we do not necessarily kill a
running terraform command immediately even if the stream is closed. The
reason for this is to allow for graceful cancellation even in such an
event. Currently the timeout is set to 5 minutes by default.
