Stop NetworkManager from updating resolv.conf
cloud-init creates /etc/NetworkManager/conf.d/99-cloud-init.conf, for NetworkManager to not update resolv.conf. However, subsequent update of NetworkManager seems to remove that file as there is no config(noreplace) directive for it. So after an update/upgrade of overcloud nodes, reboot would cleanup the dns entries. cloud-init do configuration only one time during first instance boot. So this would ensure resolv.conf is not touched during subsequent reboots. Change-Id: I989e3f1d14fd33e97933032111cf48166dc5f50c (cherry picked from commit 6881079d12a9fb2cf752a5f56116c1b4d3a7b75d)
