Failures in IA Deployment aren't reflected in the API

[nyuuyn]

Current Behavior:
Basically, when the IA Engine tries to deploy an IA and fails (which is clearly stated in the logs), in the UI it is still marked as a successful deployment.

Expected Behavior:
An error should be thrown from the API to UI

Steps to Reproduce:
Take any CSAR, configure the container with wrong endpoints for the Tomcat, deploy the CSAR, see the deployment marked as successful although no IA was ever deployed.

System Information:
Tested with local setup (Container in Eclipse, Tomcat and BPS running locally) on Mac

I would love to contribute here if this is not being worked on already.
