This patch is masking the services that are started when the Ironic Python Agent ramdisk boots up but are not needed. Consequently, this may save us some seconds at startup time. The list of services disabled are: update-engine, update-engine-stub, resize-btrfs, locksmithd, fleet and etcd. Change-Id: Ib91ec2d0c69b1724170d38dea5d38248145c5d9f
