Title: Closes #5102 - Show stacktrace of startup exception

https://github.com/elasticsearch/elasticsearch/issues/5102

This makes it a lot easier to debug a problem
like

{2.0.0-SNAPSHOT}: Startup Failed ...
- NumberFormatException[For input string: ""]

because now you see from where the error comes
from (which might be from a plugin!).
