Environment OS_AUTH_TYPE doesn't work

[TommyLike]

Currently cinderclient will not recognize the environment variable 'OS_AUTH_TYPE ' even if it's configured.
configuration file
```
export OS_AUTH_TYPE=noauth
export CINDER_ENDPOINT=http://10.229.50.225:8776/v3
```
cinder list
```
ERROR: You must provide an authentication URL through --os-auth-url or env[OS_AUTH_URL].
```

OS_AUTH_TYPE was removed in 2.2.0 and replaced with OS_AUTH_SYSTEM, luckily this was planned and OS_AUTH_SYSTEM is also valid in 2.1.0; so we should be pretty safe here. Just make sure to set OS_AUTH_SYSTEM and things should work.

We'll need to update the example rc file in block-box to reflect this.

    Replace OS_AUTH_TYPE with OS_AUTH_SYSTEM in rc

    We've removed OS_AUTH_TYPE support in favor of OS_AUTH_SYSTEM
    as of 2.2.0. This change just updates the example rc file to
    reflect that. While we're at it we'll also go ahead and update
    the example entry for the endpoint IP to point to the localhost.

    Of course this will need to be changed if you're running the
    client on a different node than the container.
