Configure the bootstrap processes on etcd, master and worker node VM as daemon process about terraform-kubernetes-installer HOT 4 OPEN

OK I think I may have fixed this in a unrelated commit. So the docker service was being started but not being enabled. (Sorry found this and meant to split it out but went on holiday and forgot)

https://github.com/oracle/terraform-kubernetes-installer/pull/75/files#diff-e91822387365c76f9ce415a2ef3aa164R24

Can you please test again as they should all come up now.

Sure, we will verify. The fix is just for etcd right?

I have tested a reboot of the etcd node but the etcd docker service didn't come back up after the restart.

docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
d064acd5e8a5 quay.io/coreos/etcd:v3.2.2 "/usr/local/bin/et..." 2 hours ago Exited (255) About a minute ago gifted_swartz

so I tried manually starting it up

so we need to specify the etcd data directory as well for it to work, so I specified the etcd_iscsi_volume_create=true during creation but I don't see the docker etcd coming up with the restart of the etcd node instance.

so I tried again manually starting it up but now I get this
2018-01-04 18:41:44.182305 I | etcdmain: setting maximum number of CPUs to 4, total number of available CPUs is 4

OK this is due to selinux which we disable reenableing on reboot.

This should fix it.
