    Optimize CentOS Erlang installation

    This patch optimizes the Erlang/RabbitMQ installation on CentOS. It
    includes:

      * Installing RabbitMQ from RabbitMQ's repository
      * Installing Erlang all-in-one from RabbitMQ's repository
      * Remove old versionlocks before applying new ones (fixes bug)

    The erlang-solutions repository is hosted in eastern Europe and has
    high latency to the USA and western Europe. Installing from that
    repository brings in over 80 individual packages, which causes
    additional delays in the role.

    The Erlang all-in-one package from RabbitMQ's repository contains
    only the Erlang bits that RabbitMQ needs. Also, it has HiPE enabled
    by default, which is recommended by RabbitMQ developers for
    better performance.
