Only conditionally import working keyring

keyring is conditionally imported if available on your platform,
however not all versions of keyring actually work. Specifically
we have global-requirements of >=2.1,!=3.3, so we know those are
the only versions we believe work.

If you are on an older platform, using system installed
python-keyring, python-keystoneclient won't install a new version,
because it's optional, but then will use a terriblely old verison,
which explodes with dbus errors.

The fix is to be more explicit on import.
