Add ironic inspector to fluentd log collection

Previously ironic inspector logs were not being collected, as they are
stored in /var/log/kolla/ironic-inspector/ rather than
/var/log/kolla/ironic/. This change modifies the fluentd input
configuration to use the correct directory.

Also adds the ironic-inspector service to the fluentd programname
rewrite rule.
