Runtime enhancements to support the same workflow/process definition name in different namespaces

[wmedvede]

Description

The runtime must be prepared to send the namespace information as part of the ProcessDefinitionEvent to facilitate the registering by the Data Index.

Implementation ideas

Similar to the kogito.service.url, we'll introduce new property kogito.service.namespace to configure the namespace. This information will be sent to the Data Index as part of the ProcessDefinitionEvent.
