 metrics-db currently has (at least) six classes providing a `main` method,
 which are invoked using six corresponding ant tasks.

 One solution for providing an executable jar:

 Add a new class `org.torproject.ernie.db.Main` as the jar's main class
 adding the following functionality:
 * calling `java -jar metrics-db.jar` will show a usage message and exit.
 * calling `java -jar metrics-db.jar <taskname>` will run the main method
 of the class called in the current ant task of the same name, i.e.,
 taskname is one of
   * bridgedescs
   * bridgepools
   * exitlists
   * relaydescs
   * torperf
   * updateindex


 Finally, remove the then obsolete ant tasks from build.xml.


 What is missing?
 Should a task be added or removed?
 Other thoughts?
