Updating HeuristicLab 3.3.5 to HeuristicLab 3.3.6 with the update service fails

[gkronber]

Will also fail for the case 3.3.6 -> 3.3.7 because we had changes in the plugin infrastructure again. #1887

There are two fundamental problems in the way how the update service is currently implemented:

• The plugin infrastructure itself cannot be updated. If the plugin infrastructure has to be changed, updating HeuristicLab plugins with the update service will result in an inconsistent state.
• The update service cannot update the application configuration. Therefore it is not possible to add/update the definition of services which are used in plugins (e.g. OKB, Hive).

These two issues cannot be fixed easily. Therefore I reject this ticket for now. We have to think about a fundamental redesign of the update service.

Created follow-up ticket #1891 for HeuristicLab 3.4.x.

To avoid any problems with the update service, I removed all plugins from the database. The update service is therefore not functional anymore for HeuristicLab 3.3.x.
