Unnecessary import of keyring leads to spurious "Failed to load keyring modules." messages

[Davanum Srinivas (DIMS)]

in a server environement where there are no keyrings, i still keep getting "Failed to load keyring modules." even on a simple "keystone --help". This is very irritating.

Looking at the code if use_keyring is false, we should not even be trying to load keyrings!!!

    Work better in server env with no keyrings

    We should not try loading keyrings if we dont' have to. We
    certainly should not print messages if keyrings are not even
    needed

    Fix for LP# 1145071
