Showing the encoding or its operators in the run is highly wasteful

[abeham]

Runs generated by solving a BasicProblem are typically larger than those that solve a HeuristicOptimizationProblem. BasicProblems define an Encoding which usually contains several operators. The Encoding and its operators are added to the parameters of each run which in turn creates a noticeable memory overhead (especially for larger experiments). Similar optimizations have been performed in the past, that e.g. operators in the run are stored only by their name (StringValue) instead of by their full type.

The patch sets the GetsCollected property to false for the mentioned parameters

Discussion at architects meeting:

• Revert BasicProblem change and instead override GetCollectedValues in Encoding and return string of Encoding

r16860: Reduced footprint of encoding in run

• Instead of the encoding instance, only its name is added to the run (necessary to change in BasicProblem)
• By default the operators parameter of an encoding is set to not be collected (change in Encoding)

I reviewed r16860 and found no problems.
