outdated APT pinnings for haproxy/ceph/ovs (with UCA)

[Dmitry Burmistrov]

Detailed bug description:
 For environments with UCA packages there are options to enable/disable APT pinning for HAProxy, RabbitMQ server and Ceph. Also there is pinning for openVswitch in preferences.d dir.
 For Ubuntu Xenial (16.04) this pinnings are outdated.
 Here are current pinnings:
root@node-2:~# cat /etc/apt/preferences.d/haproxy-mos.pref
# This file is managed by Puppet. DO NOT EDIT.
Explanation: osnailyfacter: haproxy-mos
Package: haproxy
Pin: version 1.5.3-*
Pin-Priority: 2000
root@node-2:~# cat /etc/apt/preferences.d/ceph-mos.pref
# This file is managed by Puppet. DO NOT EDIT.
Explanation: osnailyfacter: ceph-mos
Package: ceph ceph-common libradosstriper1 python-ceph python-rbd python-rados python-cephfs libcephfs1 librados2 librbd1 radosgw rbd-fuse
Pin: version 0.94*
Pin-Priority: 2000
root@node-2:~# cat /etc/apt/preferences.d/rabbitmq-server-mos.pref
# This file is managed by Puppet. DO NOT EDIT.
Explanation: osnailyfacter: rabbitmq-server-mos
Package: rabbitmq-server
Pin: version 3.6*
Pin-Priority: 2000
root@node-2:~# cat /etc/apt/preferences.d/openvswitch-mos.pref
# This file is managed by Puppet. DO NOT EDIT.
Explanation: osnailyfacter: openvswitch-mos
Package: openvswitch*
Pin: version 2.4.0*
Pin-Priority: 2000
root@node-2:~#

 And current package version:
ii openvswitch-common 2.5.0-0ubuntu1
ii openvswitch-switch 2.5.0-0ubuntu1
ii rabbitmq-server 3.6.1-1~u16.04+mos2
ii haproxy 1.6.3-1~u16.04+mos2

 This might affect other pinnings and packages - we should make this part fixed/updated/refactored/etc.

 This issue should be researched in the context of Ubuntu 16.04 Xenial Xerus.

Steps to reproduce:
 Deploy env with this instructions - https://mirantis.jira.com/wiki/pages/viewpage.action?pageId=273614357#MigrationtoXenial16.04notes(@dmburmistrov)-Howtodeploy
 Or wait for finalized custom ISO for 16.04 (current flow sometimes fails).
Expected results:
 Fuel uses actual pinnings - only for needed packages, with proper versions.
Actual result:
 Nodes have invalid pinnings.
