ProcessBuilder: Generic module to build processes within code

[phstratmann]

Objective of issue: In the repo, Processes are produced on the fly in the SolverProcessBuilder.
That's a feature which should not be hidden in the optimization library, but should be a generic tool in Lava.
In addition, in builder.py, the decorators are currently replaced in this way:
setattr(solver_model, "implements_process", self.solver_process) # Get requirements of parent class super_res = solver_model.required_resources.copy() # Set new requirements not overwriting parent class requirements. setattr(solver_model, "required_resources", super_res + requirements) setattr(solver_model, "implements_protocol", protocol)

That will work with the current decorators; but future pushes to the decorators may break it.

Lava version:

• 0.3.0 (feature release)

@phstratmann should this rater be split in a lava issue and a lava-optimization issue?

[mathisrichter]

This issue covers two points:

1. A feature request for something that can generate Lava Processes on the fly. This should be filed in the lava-nc/lava repository.
2. An idea to make the lava-optimization code more future-proof, which would be a feature request to be filed in lava-nc/lava-optimization.
   @phstratmann Could you please change the stories accordingly?
