PolicyManager: Extend the EvaluationContext to handle IsTimeGreaterThan()
The EvaluationContext needs to know the point in time where the
current evaluation of a policy request started to be able to handle
time based values like IsTimeGreaterThan() efficiently and the
timeout for the current evaluation. This patch adds such method to
the EvaluationContext class and exposes a new ResetEvaluation()
method to allow restart an evaluation. The restart of an evaluation
is independent from the notification mechanism implemented by
RunOnValueChangeOrTimeout().
The documentation on the header file is updated and extended with an
example of the workflow.
