Whereas nova has the --insecure option, but doesn't have such a nice
error message indicating that certificate verify failed :)

Thoughts? I think it would be great to get:

1) Some consistency between the two tools regarding how they indicate
that cert verification failed

2) An --insecure option consistent in all clients for use in
test/non-prod environments that have self-signed certs

3) The ability for all CLI tools to support a --version option (or
version command)

Do people agree?

Best,
