Don't do it.
os-client-config's plugin loading has been causing this pain for a long
time, removing the KSC hack-around in o-c-c unmasked this again. So when
auth is not reuired, just don't let o-c-c do any plugin loading at all.
Ever.
Of course, this shouldn't be in OSC either, but we have to do this until
the equivalent fix lands in osc-lib, is released and makes it into the
global requirements minimum version.
