cloud-init service still persists after deployment

[Sergey Kolekonov]

9.0 ISO #54

cloud-init service persists after cluster deployment because its package is removed instead of being purged. It leads to long rebooting of all nodes (3+ minutes) as cloud-init service still tries to get configuration (a screenshot is attached)

    Disable cloud-init services after provisioning

    cloud-init services should be disabled after provisioning, otherwise they will
    try to get configuration on each reboot and increase booting time to ~2 minutes

Found that on 8.0 cloud-init is installed again, because of this commit:
https://github.com/openstack/fuel-library/commit/b78251b26984ddaca211f973ec4c2f88eafe992b

On 7.0 it was
/var/log/apt/history.log
Start-Date: 2015-10-05 22:24:32
Commandline: /usr/bin/apt-get -y -q remove --purge cloud-init
Purge: cloud-init:amd64 (0.7.5-0ubuntu1.12)
End-Date: 2015-10-05 22:24:32

On 8.0
/var/log/apt/history.log
Start-Date: 2016-03-16 13:59:51
Commandline: /usr/bin/apt-get -y -q remove cloud-init
Remove: cloud-init:amd64 (0.7.5-0ubuntu1.17)
End-Date: 2016-03-16 13:59:52

So on 8.0 cloud-init is actually present:
dpkg -L cloud-init
/etc
/etc/rsyslog.d
/etc/rsyslog.d/21-cloudinit.conf
/etc/profile.d
/etc/profile.d/Z99-cloud-locale-test.sh
/etc/init
/etc/init/cloud-init-local.conf
/etc/init/cloud-final.conf
/etc/init/cloud-init.conf
/etc/init/cloud-log-shutdown.conf
/etc/init/cloud-init-nonet.conf
/etc/init/cloud-config.conf
/etc/init/cloud-init-container.conf
...

And nodes are waiting for it on reboot... And if there is a metadata server in the network it may response with the script and, e.g. wipe disks on the node)

Verified on MOS 8.0 + MU3 updates.

Steps to verify:
1. Reboot node and observe logs for this node in VNC.

Before updates:
During reboot 'cloud-init-nonet' increases booting time to 120 sec (as in comment #1).

After updates:
During reboot 'cloud-init-nonet' was not started. Reboot takes 120 sec less time.
