Kayobe has a workaround for CentOS cloud images which contain a bogus nameserver entry in /etc/resolv.conf. By setting overcloud_host_image_workaround_resolv_enabled to true, the entry would be removed. Previously we removed a specific IP address - 10.0.2.3 - that was present in the CentOS 7 images. However, it seems that CentOS 8 images have a different IP - 192.168.122.1. This change fixes the issue and becomes resilient to future changes by matching any IP address. This should be fairly safe, since this workaround is opt-in. Change-Id: I9323a38cb2bb627ff56f5713900be00595ea8d4b Story: 2006574 Task: 39484
