Currently the client configuration is managed in 'add' and 'remove' step handlers. This causes two problems:

1) Other services can not depend on this configuration being ready.
2) Injection can't be used to obtain the ServerConfig.

The solution is to have the add and remove step handlers start and stop a service (respectively). This service is dependent on the CONFIG_SERVICE and has the ServerConfig injected. Other services that need the ClientConfig can depend on this service.
