model-importer.properties should be deprecated and removed

I noticed that the file $OPENNMS_ETC/model-importer.properties now has a new property in its content (since when I don't know, sorry). These properties should not be used with Provisiond and this setting should be moved to provisiond-configuration.xml as were the other properties that were originally in this file. The property I refer to is:

1. Where to store requisition and foreign source data
   importer.requisition.dir = /opt/opennms/etc/imports
   importer.foreign-source.dir = /opt/opennms/etc/foreign-sources
