    Install sensu from centos-opstools

    This should help improve stability overall, in exchange for slightly
    older package version.

    Cap all the sensu plugins to their known major version that works with
    the ruby interpreter shipped with the current version of
    rhel/centos/oraclelinux -- currently ruby 2.0. All sensu plugins use
    semantic versioning so we're assured they don't introduce breaking
    changes in the capped major version.
