LL-207
* cloud service for deploying other services during run-time
* allowed to run sss with/without the possibility to automatically start new instances (i.e. certain services)
* fixed SSJSONLD init for adapter rest
* sss adapter rest handleStandardJSONRESTCall catches the deployment of remote services on possibly different machines now
* created copy methods in configs in order to derive master config and adapt it to remote service deployment
* services use methods getConfForCloudDeployment for creating respective configs for cloud deployment
* separated core service configs from simple service configs
* changed URI schema for type user to simple IDs instead of .../user/id
* finally moved publishClientOps, publishServerOps from service implementation abstract classes to services' interface
* registering services being available in general (e.g. for deployment) (additionally to service ops) when initializing services, hence the master node knows all services available; the nodes all services running on respective machines
