Explicitly configure credentials used by ironic to access other services
Explicitly configure credentials used by ironic to access other services

Using keystone_authtoken credentials for this purpose is deprecated, and also
prevents ironic-conductor from being used as a separate role.

As a side effect, this change makes it possible to potentially enable
ironic-inspector support in the future (it's not enabled yet).
