Upgrade DQ2 0.2.11 site services (July 13 2006)

There are >5 updates to 0.2.11 since it's first released. It is recommended 
to upgrade your site installation at this time. I think the best/simplest approach 
is as the following:
- stop cron by running 'crontab -r', goto dq2 install root area.
- wait for the Fetcher and SubscriptionHandler processes to finish if
  there are any. If SubscriptionHandler does not go away within 15
  minutes, try to do:
      python DQ2/siteservices/executor/classic/StopSubscriptionHandler.py -w
  if StopSubscriptionHandler fails, use 'kill -9'.
- Run mysql client to connect to your 'queued_transfers_cat' as defined in
  config/<sitename>/executor_conf.py, do
      drop database queued_transfers_<xxx>;
      create database queued_transfers_<xxx>;
- mv DQ2/ to DQ2-old.
- run ./install_dq2.sh
- recreate transfer status tables with new schema by doing:
      source config/<sitename>/environment.sh,
      python DQ2/siteservices/executor/classic/RecreateDatabase.py
- in config/<sitename>/executor_conf.py, add site_callbacks for monitoring purpose
  site_callbacks = {
      CallbackType.MONITOR_SUBSCRIPTION:
      ['http://atldq02.cern.ch:8000/dq2/ws_transfer_monitor/dispatch_guids_info'],
      CallbackType.FETCHER_VUID_COMPLETE:
      ['http://atldq02.cern.ch:8000/dq2/ws_transfer_monitor/dispatch_vuid_complete'],
      CallbackType.FILE_DONE:
      ['http://atldq02.cern.ch:8000/dq2/ws_transfer_monitor/dispatch_file_done'],
      CallbackType.ERROR:
      ['http://atldq02.cern.ch:8000/dq2/ws_transfer_monitor/dispatch_error'],
      }
- in DQ2/siteservices/tool/fts/fts.py, replace with your true FTS_PWD 
- start cron by 'crontab <tabfile>'
