Improve tests and distributed error notifications

- Tests now perform faster
 - Tests will run on supported GPU platforms
 - Configuration has known issues related to setting up a working
   directory for an embedded client
 - Introduce a Skeletonize node that solves many problems with Canny
 - Improve behavior of exception reporting
