mistral: align parameters with undercloud

- To be aligned with how undercloud was configured, let's change some
defaults in Mistral Engine:

mistral::engine::evaluation_interval: 120
mistral::engine::older_than: 2880

- 2 new parameters are provided:

    MistralEvaluationInterval is a new parameter that allow to configure
    how often will the Mistral Executions be evaluated.
    For example for value 120 the interval will be 2 hours (every 2 hours).

    MistralFinishedExecutionDuration is a new parameter that allow to configure
    how Mistral will evaluate from which time remove executions in minutes.
    For example when set to 60, remove all executions that finished a 60 minutes
    ago or more.
    Note that only final state execution will remove (SUCCESS/ERROR).
