    Remove pause/resume logic

    This is a subordinate charm and since a recent
    commit [1] it shares a list of its services with
    the principal charm nova-compute, which has now
    the responsibility to pause and resume services. [2]

    The ceilometer-agent-compute service has a
    dependency to the nova-compute service anyway, so
    it is impossible for this charm to resume its
    service if its principal charm nova-compute is
    paused. This is what also led to errors in
    ceilometer-agent's post-series-upgrade hook. This
    hook attempted to resume its service although
    the principal service was still paused. Removing
    this logic entirely solves this issue.

    Validated by running openstack-upgrade and
    series-upgrade tests. [3]
