  - [nosdn-noha] Meet EPA testcases requirements - pt2

    JIRA: FUEL-385

    After successfully merging patch
    https://gerrit.opnfv.org/gerrit/#/c/61417/ a user can deploy
    os-nosdn-nofeature-noha scenario with numa topologies on compute nodes.

    In order to be able to run the EPA testcases, there are still some
    requirements (see [1]):
      - Testcases expect compute nodes to have hugepages enabled
      - Testcases expect compute nodes to have cgroup-tools package
        installed
      - Testcases expect to have NUMATopologyFilter added to
        enabled_filters in /etc/nova/nova.conf of the controller node

    This patch tries to meet the above requirements. First, it installs
    the cgroup-tools package on compute nodes. Secondly, it overrides the
    default enabled_filters of openstack nova salt package by appending
    NUMATopologyFilter in the end (see [2], [3]).
