BUG#: 9953
TITLE: InstancedFilter call in ResponseStressTestCxx provider causes failure in pullop and sometimes server

DESCRIPTION: Modify CIMPropertyList to add function that tests for
existence of property in CIMPropertyList without assigning the Array
of CIMNames to an external variable. Change CIMObjectRep to use this
function for instanceFilter and the ResponseStressCxx provider to
enable instanceFilter (and make more efficient)

/**
    The CIMPropertyList class represents a propertyList parameter in a CIM
    operation request, as defined in the DMTF Specification for CIM
    Operations over HTTP.

    <p>This class consists of an array of property names and a flag
    indicating whether the list is null.  A null property list indicates
    that no filtering is performed on the basis of this parameter.  A
    non-null property list indicates that any property not specified in the
    list is to be filtered from the CIM operation response.  (An empty
    property list implies that all properties should be filtered from the
    response.)

    <p>A null property list is created by using the default constructor or the
    clear method.  An empty property list is created by setting the value to
    an empty Array.
