Converts the legacy {@link CommonAttributes#FILTER filter} to the new {@link CommonAttributes#FILTER_SPEC filter
spec}.

@param value the value to convert

@return the filter expression (filter spec) or an empty String the value is not
{@linkplain ModelNode#isDefined() defined}

@throws org.jboss.as.controller.OperationFailedException if a conversion error occurs
