show help when calling without arguments

When calling cinder without arguments you'll receive the following
output:

error: too few arguments
Try 'cinder help ' for more information.

With this change the help is also shown when calling cinder
without arguments. I think that's the expected behavior.

Add list-extensions capability to cinderclient.

Implements the list extension functionality from novaclient
written by harlowja (Change-Id: I5b72f5ea73c00f1c1a0f09f670d744c820e05837)

This provides a mechanism to view available extensions, and also
starts actually using the cinderclient contrib dir.

Move from nose to testr.

Granted - this takes the test suite from 3 seconds to 1 second... but there
are a bunch of other ways (correctness) that testr is better than nose.

Removed tests/v1/utils - it was not being used anywhere.
