IHA template fails to send heartbeat due to no credentials

[Steven Hardy]

The IHA template gets stuck in a bad loop continuously replacing the instance, because cfn-push-stats cannot authenticate with the CloudWatch API, since there is no /etc/cfn/cfn-credentials file - the template needs credentials adding similar to the HA template

    heat templates : IHA HeartbeatFailureAlarm should be Ref

    cfn-push-stats reference to HeartbeatFailureAlarm should be a
    Ref not a hard-coded string, or the engine fails to find the
    watch because the name lacks the stack prefix

    heat templates : fix IHA HeartbeatFailureAlarm during instance build

    The HeartbeatFailureAlarm triggers prematurely while the instance is
    building, because cfn-init doesn't create the files (hence the
    heartbeat cron-job) until after the packges are all installed.
    If we make the HeartbeatFailureAlarm depend on the WaitCondition, it
    won't be created until the instance is fully built.

    fixes bug 1100719

    heat engine : watchrule don't run rule for every SampleCount

    We should not be triggering a run_rule (which is an alarm action)
    for every datapoint when the SampleCount statistic is specified,
    otherwise e.g IHA instances get replaced every heartbeat signal!
    run_rule should only be called in response to a rule evaluate(),
    or an explicit override via set_watch_state()
