S3000 REST webservice support

While our commercial framework for laboratories, S3000, had support for making predictions via webservices for a long time, that was limited to asynchronous ones: a webservice endpoint receives data coming in and, once the predictions have been generated, the results get forwarded to another webservice.

With recent changes to the codebase, it is now possible to offer synchronous REST webservices as well. In order to reduce latency as much as possible, provenance logging under the hood has been modified to have a much higher throughput that no longer impacts the speed of the predictions.

Thanks to the plugin architecture of S3000, customer-specific webservices can be implemented and deployed with minimal effort.
