refactor the biz.netcentric.cq.tools.actool.helper.QueryHelper.java to use SQL2 and optimize Queries to use existing AEM indexes about accesscontroltool

I also suggest to create a package with new oak:index for such query statements
SELECT * FROM [rep:ACL]
like

<actoolRepACL
    jcr:primaryType="oak:QueryIndexDefinition"
    declaringNodeTypes="{Name}[rep:ACL]"
    entryCount="{Long}9223372036854775807"
    nodeTypeListDefined="{Boolean}true"
    propertyNames="{Name}[jcr:primaryType,jcr:mixinTypes]"
    reindex="{Boolean}false"
    reindexCount="{Long}1"
    type="property"/>

As result the actool runs now for us with oak 1.0.13, MongoDB and index above about 6 min on production instead of more as 1 hour early.
