Dean Troyer 10670d1bad Add support for OS_* environment vars
Add the OS_* env variables to mirror the NOVA_* vars; example:
setting OS_USERNAME will override NOVA_USERNAME in the clients and
tools, but if left unset it defaults to NOVA_USERNAME.

Adds exercises/client-env.sh to test operation of command-line
clients with only the OS_* variables set

Addresses bug 897304, http://wiki.openstack.org/CLIAuth
