prompt: respect GIT_TERMINAL_PROMPT to disable terminal prompts

Browse Source 
If you run git as part of an automated system, you might
prefer git to die rather than try to issue a prompt on the
terminal (because there would be nobody to see it and
respond, and the process would hang forever).

This usually works out of the box because getpass() (and our
more featureful replacements) will fail when there is no
tty, but this does not cover all cases. For example, a batch
system run via ssh might have a tty, even when the user does
not expect it.

Let's provide an environment variable the user can set to
avoid even trying to touch the tty at all.
