keystone cannot update a password with the icehouse client

[Matt Fischer]

keystone's library ruby code relies on the output from keystone-client to decide if puppet should change the password. This apparently worked before, but the output has changed with newer clients.

A return of nil from this code is apparently what triggers a new password to be set:
   return nil if e.message =~ /Not Authorized/

However, newer clients do not return that string, they return:
"The request you have made requires authentication. (HTTP 401)"

The ruby code needs to be updated to handle both.

    update passwords for users.
