Return the SQL schema for all DS queries in request (to provide information to AI / Autocomplete for SQL expressions).
All DS queries are treated as if they were inputs to SQL expressions in terms of conversion, regardless if they are selected in a query or not.
Requires feature toggle queryService = true
Endpoint is apis/query.grafana.app/v0alpha1/namespaces/default/sqlschemas

This is because MySQL doesn't support storing of NaN valuels, and therefore go-mysql-server isn't going to either.
Float fields/columns are always mapped to be nullable now, otherwise we would have to replace NaN/Inf with 0.
sql_expression_query_length_limit
Set the maximum length of a SQL query that can be used in a SQL expression. Default is 10000 characters. A setting of 0 means no limit.
* parse via sse
I need to figure out how to handle the pipeline.execute with our own
client. I think this is important for MT reasons, just like using our
own cache (via legacy) is important.
parsing is done though!
* WIP nonsense
* horrible code but i think it works
* Add support for sql expressions config settings
* Cleanup:
- remove spew from nodes.go
- uncomment out plugin context and use in single tenant flow
- make code more readable and add comments
* Cleanup:
- create separate file for mt ds client builder
- ensure error handling is the same for both expressions and regular queries
- other cleanup
* not working but good thoughts
* WIP, vector not working for non sse
* super hacky but i think vectors work now
* delete delete delete
* Comments for future ref

* ds-querier: handle execute errors better
* fix: change how GetResponseCode works to return 418 if rsp is nil
418 is a bit of an easter egg which in this case works since we don't
have an rsp but we do know something went wrong, so a 200 won't work.
Also changed this to return the code in the frame, not sure why we
weren't.
* tests: fix GetResponseCode tests
* log no rsp case
* bring back og error log
