  64  * <p>
  65  * A main class which may be used to start the provisioning server with an "embedded" Jetty server. Configuration is
  66  * done via the properties file <i>provserver.properties</i>, which should be in the CLASSPATH. The provisioning server
  67  * may also be packaged with a web.xml and started as a traditional webapp.
  68  * </p>
  69  * <p>
  70  * Most of the work of the provisioning server is carried out within the eight servlets (configured below) that are used
  71  * to handle each of the eight types of requests the server may receive. In addition, there are background threads
  72  * started to perform other tasks:
  73  * </p>
  74  * <ul>
  75  * <li>One background Thread runs the {@link LogfileLoader} in order to process incoming logfiles.
  76  * This Thread is created as a side effect of the first successful POST to the /internal/logs/ servlet.</li>
  77  * <li>One background Thread runs the {@link SynchronizerTask} which is used to periodically
  78  * synchronize the database between active and standby servers.</li>
  79  * <li>One background Thread runs the {@link Poker} which is used to notify the nodes whenever
  80  * provisioning data changes.</li>
  81  * <li>One task is run once a day to run {@link PurgeLogDirTask} which purges older logs from the
  82  * /opt/app/datartr/logs directory.</li>
  83  * </ul>
  84  * <p>
  85  * The provisioning server is stopped by issuing a GET to the URL http://127.0.0.1/internal/halt using <i>curl</i> or
  86  * some other such tool.
