Display query errors from ElasticSearch

[PBMikeW]

Currently Elastic Query run does not return errors. (Cost me a chunk of time when converting from lucene to elastic)

#16938

For discussion. Honestly not sure the best way to handle this.

Options:

1. Do we want to bother with this or leave it to users to try and dig into logging? (Error is logged in ES module).
2. We could just let the error hit the front end. (however one query error breaks whole page)
3. We swallow any errors on API and helpers and keep the exception bubbling up to the admin ui.
4. We use some sort of notification instead.

ElasticQueryService rethrows to bubble error up to admin UI and to ApiExceptionHandlingFilter.

New ApiExceptionHandlingFilter to return nice problem details on API exception.

Swallow error on razor helper. Might need to do liquid filter too. Optionally could not swallow error and razor would return:

I think I would use a 400 for this one.

We could also pass an error code along with the error string that we could document. Just to make a distinction between 500 and 400.
