///////////////////////////////////////////////////////////////////////////////
//
// This class defines the ShutdownService necessary to process the shutdown
// request to gracefully shutdown the CIMServer.
//
// In order to shutdown the CIMServer gracefully, the CIMServer state
// information must be maintained.
//
// The state of the CIMServer is kept in the CIMServerState object.  After
// CIMServer starts up, the CIMServer state is set to RUNNING.  When a
// shutdown request is received by the ShutdownService, the CIMServer state
// will be set to TERMINATING.
//
// Whenever a request comes through a client connection, before the request
// is being routed off to the appropriate message queue, the CIMServer state
// is checked.  If the state is set to TERMINATING, this means CIMServer is
// in the process of being shutdown, an error response will be sent back
// to the client to indicate that the request cannot be processed due to
// CIMServer shutting down.
//
// In order to determine if the CIMServer is servicing any CIM requests at
// the time of a shutdown, CIMServer keeps track of the number of CIM requests
// that are outstanding.  This request count is kept in the HTTPConnection
// object.  The request count is incremented everytime a request comes through
// a client connection, and is decremented everytime a response is sent back
// to the client.
//
// Before the ShutdownService shuts down the CIMServer, the request count is
// checked to determine if there are any outstanding CIM requests being
// processed.  If there are no requests outstanding, the CIMServer will be
// shutdown.  If there are requests outstanding, the ShutdownService will
// wait periodically until the requests are all processed or until the
// timeout expires before shutting down CIMServer.
