    [2203] a piggy back fix: prevent redundant initial data configuration.
    
    this addresses the issue described in #2291.  Still not really clean,
    but thanks to boost::bind we can centralize all the code logic in the
    callback, so I think it's now less likely that we forget cleaning it up
    when the hack is not necessary.

    [2203] changed configurator class to a simple function.
    
    as it's now completely stateless and can work independently.
    the common specialization for the main implementation is defined in a
    new created .cc file.

    [2203] pass server obj to configurator's reconfigure().
    
    now the configurator class is completely stateless.

    [2203] refactoring 2nd step: configurator can now be a separate object.
    
    i.e., it's not a singleton any more.
    testReconfigure() method isn't needed any more because it doesn't hold
    CC session internally.
    DatasrcConfiguratorTest.initialization test currently fails and is
    disabled for now.  The plan is to make the class completely stateless,
    at which point we don't even have to think about initialization or cleanup,
    and then the test will be able to be removed.

    [2203] changed the callback type of addRemoteConfig to boost::function.
    
    this will make it more convenient, e.g., by allowing the caller to pass
    boost::bind encapsulating a class object and a class method.
    
    boost::function is upper compatible to function pointer, so it doesn't
    ensure source-level compatibility.
    
    the functor overhead shouldn't matter in this context, and since this module
    already uses boost::function this change doesn't introduce additional
    dependency.

    [2203] refactoring 1st step: move session obj outside of datasrc configurator.
