* Revert "fix(error): unsupported value: +Inf" error not handled gracefully (#20250)"
This reverts commit 6ac0bb3fe3.
* fix: No infinite recursion on write error
If there is some error writing to the response writer, we
would previous have infinite recursion.

JSON marshalling errors should be returned properly formatted in JSON
like other errors. This fix formats marshalling errors the same way
influxdb formats other query errors.
Fixes https://github.com/influxdata/influxdb/issues/20249
If the columns change between series, it will now act as if it was a new
statement id and reprint the headers. This only happens with show
diagnostics at the moment and we shouldn't add this functionality
anywhere else anyway.
The query killing functionality depends on the ResponseWriter exposing a
CloseNotify method. Since we wrap the http.ResponseWriter, the new
struct does not have that method and the HTTP handler would skip past
calling that method.
Instead of duplicating `Flush()` and `CloseNotify()` for every response
formatter, we will unify all of that under a single struct and create
formatters instead.
Also, fixes a bug where the header information from a query would not be
returned until some other data was returned with it because of
buffering and another bug in the gzipResponseWriter that wouldn't flush
the actual underlying ResponseWriter.
CSV doesn't offer a way to separate different sheets from each other and
it doesn't really have a standard format. We separate sheets with a
newline so they can be imported into something like Excel or LibreOffice
more easily.
The number of columns for each sheet is inferred from the first returned
row in each statement since they should all be the same.
The `Content-Type` header is meant to say what the content type of the
request is supposed to be and `Accept` is used to ask for a specific
content type. I messed this up and used `Content-Type` instead of
`Accept`. This works with `GET` requests accidentally, but `POST`
requests stop working.
