Cinder api version detection fails

[Randall Burt]

Cinder client plugin API version detection will fail when the EndpointNotFound exception is thrown from keystone client and not from cinderclient.

[Randall Burt (randall-burt)]

Turns out that when Cinder v2 support was added, the "fake" keystone client was changed to raise Cinder exceptions when a url wasn't found instead of the proper keystone exception.

    Catch correct exception for Cinder api version detection

    Catch the EndpointNotFound exception raised by Keystone rather
    than the one thrown by Cinder since keystoneclient raises keystone
    exceptions and not cinder exceptions. Also update the fake
    keystone client to mirror this behavior.
