Error handling for questionnaire rendering

[Tarun-Bhardwaj]

Is your feature request related to a problem? Please describe. We should triage all the exceptions we through during questionnaire rendering and figure out if we do want to throw exceptions or handle errors in a more lenient way - so that we don't get client applicaitons crashing all the time.

This is more of a triage and design task, there will be some code change at the end, but I think those things will be easy to do.

One artifact to produce as part of this issue is a design that says, for example: for malformed questionnaires, we will know an illegal state exception, but for questions missing a link id, we will log a warning etc etc...

This will invovle talking with implementers.

I think to properly document all possible exceptions and edge cases will require a huge amount of effort and ongoing maintanance. In reality, I don't really believe the benefits here justify the cost. Closing for now. Obviously can reopen if there's a stronger need.
