Quarkus: non existing nearbyDistanceMeterClass should fail fast the build

This config:

  <localSearch>
    <unionMoveSelector>
      <changeMoveSelector>
        <entitySelector id="entitySelector1"/>
        <valueSelector>
          <nearbySelection>
            <originEntitySelector mimicSelectorRef="entitySelector1"/>
            <nearbyDistanceMeterClass>THIS_DOES_NOT_EXIST</nearbyDistanceMeterClass>
            <parabolicDistributionSizeMaximum>80</parabolicDistributionSizeMaximum>
          </nearbySelection>
        </valueSelector>
      </changeMoveSelector>
...

builds fine and gives this exception at runtime:

java.lang.IllegalArgumentException: The nearbySelectorConfig (NearbySelectionConfig()) is nearby selection but lacks a nearbyDistanceMeterClass (null).

That's dangerous. Luckily runtime fail on it, but it could have also silently ran - running something differently at runtime than what the user asked for, which is basically lying to the user.

If optaplanner-quarkus fails to do it's job, for example because that nearbyDistanceMeterClass "THIS_DOES_NOT_EXIST" doesn't exist, it should fail fast during the build already.
