Allow pinning of infrastructure package versions

[Jesse Pretorius]

In order to assist with providing a supportable and predictable infrastructure, it would be useful to be able to pin infrastructure (eg: mariadb, rabbitmq, lxc, libvirt, elasticsearch, logstash) packages to specific versions.

    Pin rabbitmq package version

    This patch implements a pinned RabbitMQ package version which is
    downloaded (by default) from the official RabbitMQ package download
    location.

    The user has the ability to use the following variables in order to
    override where the package downloads from and what version is
    downloaded:
     - rabbitmq_version: the package version
     - rabbitmq_repo_url: the base url to download from
     - rabbitmq_package_url: the full url including the base, the path and
       the package file name

    Allow the pinning of apt package versions

    This patch implements the capability to pin package versions using apt
    preferences. This prevents the unwitting upgrading of packages when
    doing general packages deployment and maintenance.

    The list of packages and versions can be overridden using user
    variables.

    For each item in 'apt_pinned_packages'
     - package: package name
     - version: package version to pin
     - priority: pin priority (default is 900, over 1000 will make apt force
       a downgrade)

    The patch also removes the usage of the LXC PPA - it was only deployed
    if the operating system was < 14.04 and the reality is that the entire
    project has not been tested on a platform < 14.04. The removal of the
    PPA is thus to reduce confusion.

    It also includes a known set of packages which are important to pin for
    a stable OpenStack deployment. The packages pinned use sources and
    version which should be available for a typical 'Long Term Support'
    time-frame.
