Is your feature request related to a problem? Please describe.

Currently, it is impossible to configure move selectors for the CH when list variables are
used, unlike chained and normal planning variables. This means it impossible
to configure a filter that prevent values that will break hard constraints
from being picked.

Describe the solution you'd like

It should be possible to configure CH move selectors when list variables are used in the SolverConfig:

  <constructionHeuristic>
    <constructionHeuristicType>FIRST_FIT</constructionHeuristicType>
    <listChangeMoveSelector>
        <filterClass>...Filter</filterClass>
        ...
    </listChangeMoveSelector>
    ...
  </constructionHeuristic>
