 Create a simplified DatasrcInfo. This one will just keep info about all
 the data sources (and, probably, the client lists as well) that are
 interesting and set of readers.

 It will be able to get all of the readers, add and remove. No need for
 state machine there. The interface could look like:
 {{{#!python
 class DatasrcInfo:
         def add_reader(id):
                 ...

         def remove_reader(id):
                 ...

         def get_readers(id):
                 ...

         def config_update(new_config):
                 ...

         def get_config():
                 """
                 The active config, stored from config_update.
                 """
                 ...

         def get_segment_params():
                 """
                 The parameters for segments to be sent to the clients.
                 """
 }}}

 It may be based (copy-pasted & edited) from the current DatasrcInfo, but
 we will still need the current one for a short while (before it is
 replaced by other tickets).
