Description

ServiceConfiguration#service parameter should be replaced with a className. All parameters, needed for service initialization, should be provided as a map of properties in ServiceConfiguration.

This approach has two advantages:

1. It allows service redeployment with changed classes, because there will be no need to deserialize the service object.
2. Changes of initialization parameters will be able to be detected, when manual redeployment happens.
