No support for transition Engine Commands

[jamesdreid]

Workflows that reference Engine commands (continue,fail,noop,retry) in the "do" section of a transition are not displayed correctly and no not run as expected. Initial testing of the "orquesta-error-handling-continue" from the examples pack does not display the "continue" command correctly on the "failed()" transition of "task1".

The workflow has an explicit "continue" listed under the "do" portion of the transition:

This command is not added to the transition properly and it cannot be added/edited to be included in the GUI. The pulldown menu only allows for the selection of tasks that have been defined in the workflow already.
