Fix unstable assertion in test_cinder_endpoints

In simple_read_only.test_cinder.test_cinder_endpoints, the test case
assumes that the first table of 'cinder endpoints' always ['nova',
'Value']. However, it is sometimes wrong.
So in this commit, the test verifies that they have 2 or more headers
and has a 'Value' header.
