Dean Troyer 6800ec378b Blueprint cli-auth: common cli args
Add --auth_url, --username and --password and OS_* env vars as
aliases to --auth, --user and --key.

Default to --auth-version=2.0 if none of --auth, --user or --key
are set or if OS_AUTH_URL is set.

Ensure trailing '/' is present in --auth so URLs are created correctly.

Fixes lp925212
