AT:

• in the ProcessVariableQueryFilter class the query to filter out the name and type of a variable is moved to a single code snippet

Context:
For each variable type a separate query to Elasticsearch is build, but for each query we always do the same query to filter filter for the variable name and type, e.g.:

boolQuery()
      .must(termQuery(getNestedVariableNameField(), dto.getName()))
      .must(termQuery(getNestedVariableTypeField(), dto.getType().getId()));
