Do not install pip when OFFLINE=True

install_pip.sh trys to fetch pip from the internet even if
OFFLINE=True. It causes stack.sh to fail if the environment
is actually disconnected from the internet. With this patch,
stack.sh skips install_pip.sh if OFFLINE=True.

Allow starting nova-compute manually

This breaks out the code that starts nova-compute into a separate
function. This will be used for upgrade testing so that we can
arrange for a nova-compute running on a different version of the
code to be running alongside the rest of the stack.

exit cleanup in functions

we should always use die instead of exit so that we know why we
failed.

Also remove instances where exit is called after die, as that is
a noop.
