Approximating Latest predictor

This predictor is used when a “latest” software stack is requested. The implementation always tries to resolve the latest software stack possible (all the packages in their latest versions). If that’s not possible given the version range requirements in the dependency graph, predictor starts to perform random “hops” across releases. This does not implement a proper backtracking algorithm but rather approximates the latest software stack resolution.

The randomness introduced causes incompatibilities with pip/Pipenv/Poetry resolver.
