Modify TripleO Ironic Inspector to PXE Boot Via DHCP Relay
Ironic Inspector dnsmasq configuration needs to be configured with multiple subnets and DHCP ranges in order to support TripleO deployments across multiple subnets. Today, only a single subnet is taken from undercloud.conf, and used to configure the dnsmasq.conf for Ironic Inspector. This feature would allow entry of multiple subnets and ranges. Routers can then be configured with DHCP relay in order to facilitate remote boot.
The changes required for minimum functionality are limited to the undercloud scripts which configure Ironic Inspector based on undercloud.conf. However, in the future Ironic Inspector may support using a Neutron network, in which case we would configure multiple subnets on the "ctlplane" network, and the dnsmasq.conf could be automatically configured. We may wish to consider revisiting this feature once Ironic Inspector supports that feature.
