Added a VerifyMojo that checks if any errors have occurred and that fails the build if any errors occurred.
The BuildImageMojo now reports errors when one of the image builds fails. These errors can be picked up by the verify task to fail the build.
When pushing an image fails, it fails the build.
When starting a container fails, log a plugin error.
With normal execution, assume no plugin errors are logged.
VerifyMojo now logs which goals have caused errors.
Added the verify goal to all integration tests and fixed the simple-it Dockerfile so that nginx is working again.
