cloud-init service is set to start before NetworkManager service starts,
but this does not avoid a race condition between them. NetworkManager
starts before cloud-init can write `dns=none' to the file:
/etc/NetworkManager/conf.d/99-cloud-init.conf. This way NetworkManager
doesn't read the configuration and erases all resolv.conf values upon
shutdown. On the next reboot neither cloud-init or NetworkManager will
write anything to resolv.conf, leaving it blank.
This patch introduces a NM reload (try-restart) at the end of cloud-init
start up so it won't erase resolv.conf upon first shutdown.
