The wizard should be able to automatically detect the plugin type from URL.
Possible approach which was available some time ago but was removed:
the feature should try to get results from each available plugin in separate threads. The plugin which return valid results is the one which should be used.
the list of possible servers shown as hint in drop down should be a list combined from all possible server
in case user selects already existing server address we can detect the plugin directly by that address - in such a case checking the results is not necessary.
in UI, the type selection control on first wizard page should be removed(or we can leave it but there should be an "auto" mode used by default).
