Skip logging only for IllegalInputException

- Add IllegalInputException to signal cases where we know the exception
  is caused by illegal input received from the requestor.
- Only skip logging for IllegalInputException instead of the superclass
  IllegalArgumentException as that is also used to signal illegal
  arguments to methods due to bugs which are otherwise hard to debug.
- Throw IllegalInputException rather than IllegalArgumentException
  where appropriate.
- Deprecated QueryException as it was only used to be able to separate
  between query string and query parameter exceptions, and not doing
  that consistently, and is in a package we don't want more use of.
- Clean up some cases where the wrong exception was thrown.
