To add a filter to the DG node, add an attribute to the SvcLogicContext.

The format of the attribute name is : <prefix> + instance-filters.instance-filter\[<offset of the filter>\] .<resource identifier>

After adding filter entry, you must specify size of filter array using following format of the attribute name:  <prefix> + instance-filters.instance-filter_length
