nova virt driver support for pre-generated auth_token doesn't work

[Chris Behrens]

The nova virt driver has a check to see if ctxt.auth_token is set and will pass it in to ironicclient, if so. However, nova.context's get_admin_context() never sets it unless you explicitly pass one in to that call.

    Add admin_auth_token option for nova driver

    The call to nova.context.get_admin_context() never sets an auth_token,
    but we should support the idea of having an admin token that's always
    known to be good. This adds a new Ironic config option for
    'admin_auth_token' and uses it if set.
