Workflow service externalization

[dewniMW]

Description:
For workflow-related operations, IS has an embedded BPEL server. BPEL has some drawbacks when it comes to its usage in IS such as runtime overhead, distribution size, and maintenance overhead. The IS should have the capability to fully externalize the workflow engine from the IS, and make any workflow engine pluggable and usable by IS.
