> Remove invoker caching from Workflow interpreter

>
> Currently in XBaya workflow interpreter we cache the invokers. THis was done
> so that if the user reruns the workflow we could reuse the invoker as well as
> we could simply use it as the service output store.
> Two issues with this are;
> 1)If the invoker is cached and at a later time reused if the time between
> reuse is more than proxy expire time, it will fail and reuse cannot be made
> anyway
> 2) Statistically cases that will reuse the invoker is much less than cases
> that it will use once. So this performance gain can be let go of a memory
> gain. If the user is rerunning, user is in the execution cycle and
> performance gain will anyway go unnoticed
> So i propose to remove the invoker map and store the output in the workflow
> node itself in the graph as possible Futures object.
