Add quickstarts which demonstrate how to signal jBPM metadata such as processInstanceId, correlationKey, and sessionId to ongoing BPM processes running as BPM service with service bindings other than SOAP. To name a few, the expected quickstarts would demonstrate how a REST client can send jBPM metadata via REST bindings, or how a RemoteInvoker can send them via SCA bindings.

Currently the only available quickstarts for BPM service are bpm-service and demos/helpdesk, but both are based only on SOAP bindings; SOAP binding has been already documented at https://docs.jboss.org/author/display/SWITCHYARD/BPM, so I believe it's better to have BPM quickstarts with other bindings for demonstrating purposes.
