When exiftool is already terminated, we no longer attempt to read from its stdout.

Exif cleaner do not support additional reads after the underling process is completed.

When the Object Storage configuration requires a MultipartUpload,
workhorse loops over the input with a LimitReader,
such loop will call Read one extra time to make
sure the input was consumed entirely.

Add success-client-cache status for image scaler

See merge request gitlab-org/gitlab-workhorse!656

Since we weren't counting cached responses as successes, in Prometheus there were showing up as `unknown`, which contributes to the overall error budget.

We need to follow up with a runbook change that also counts cached responses as successes.

When an upload (e.g. a CI artifact) reaches the maximum file size limit,
uploads via S3 would return a 500 error to the user. This made it
difficult to understand why the upload failed.

This was happening because the `hardLimitReader` was aborting the
transfer with `ErrEntityTooLarge`, but this error was wrapped in layers
of AWS errors. Since none of these AWS errors were understood by the
file handler, a 500 error was returned.

To fix this, AWS has a way to retrieve the original error. We now
recursively go down the error stack to find the root cause.

Note that there is an open issue in the AWS SDK to make this easier with
Golang (https://github.com/aws/aws-sdk-go/issues/2820).

to help detect accidental exposure of secrets such
as API tokens and cryptographic keys in commits.

Implement conditional GETs for image resizer

See merge request gitlab-org/gitlab-workhorse!647

We now set a `Last-Modified` header based on either local
file timestamps or the respective header returned from an
object storage provider.

Use detected file format for image scaler

See merge request gitlab-org/gitlab-workhorse!651

Make decisions based on what Go's `image.DecodeConfig`
tells us the image format actually is
instead of using the data sent from Rails app.

Rework image scaler tests

These looked misaligned. According to production logs, we currently serve 99% of all those requests in less than 200ms.
